This unit is available in two types: a propane and a natural gas grill. The model flaunts four high-grade steel burners. It can deliver fuel efficiency ratings of 48,000 British Thermal Units (BTUs) every hour. The unit also boasts a side burner and a sear station for a superb grilling experience.

What’s more, the Weber Genesis II S-435 comes with two durable tables on the side that have cohesive tool storage hooks. It also has a cabinet where you can store some of your grilling tools.

Napoleon Grill Prestige 500 RSIB

The Napoleon Prestige 500 RSIB is part of the Prestige Series, which features four grilling packages. Napoleon markets this specific unit as a comprehensive grilling set because of its feature-loaded design.

Like the Weber Genesis II S-435, the unit has four top-quality main burners that can deliver 12,000 BTUs. It also has a rotisserie rear burner that provides 18,000 BTUs and an infrared burner that produces 14,000 BTUs. The four main burners connect to the rear and front burners.

Features Face to Face

Brand History

Weber-Stephen Products LLC has been in business since the 1950s. It is a private-owned producer of charcoal, gas, electric grills, and grilling accessories. George Stephen Sr. established the company due to his desire to make grills a staple during family cookouts. His lidded grills were a hit during the 1960s and 1970s, and his products were featured on TV.

Napoleon Grills is a few years younger than Weber-Stephen Products LLC. The company started in 1976 as a small-time metal fabrication enterprise in Canada, which broadened into manufacturing grills after a few years. With their quality and durable designs, Napoleon easily became one of the leading grill manufacturers in North America.


Considering that Weber and Napoleon are two renowned brands in the industry, their products can be relatively costlier than those of other small-time manufacturers. Napoleon and Weber both put a premium on the quality and make of their grills and accessories. They use high-grade materials and add top-notch features that make the units stand out in the market.

At present, the Weber Genesis II S-435 is available for $1,249, while Napoleon Prestige 500 RSIB is available for $1,499.

In general, Weber grills tend to be pricier than Napoleon, but the price range varies from one unit to another. Napoleon and Weber both offer some affordable options.

Cooking Space

Comparing these specific models based on the grilling space, the Napoleon Prestige 500 RSIB wins over the Genesis II S-435. The Napoleon Prestige 500 RSIB has a total cooking space of 900 square inches, and the manufacturer claims that it can grill up to 30 hamburger patties at once. This makes the grill an efficient option if you are planning to feed a big group of people during your cookout parties.

The Weber Genesis II S-435 is slightly smaller at 844 square inches of cooking area. This includes its primary cooking space of 646 square inches and warming rack area of 198 square inches.

Grill Grates

Both Weber and Napoleon use stainless steel cooking grates that provide top-notch heat retention. This helps in achieving fast and even grilling. However, we prefer Weber’s grates over Napoleon’s for several reasons.

The Weber Genesis II S-435 prides itself on durable 7mm steel rod grill grates. Weber’s grates allow for even heat distribution, so overheating won’t be a problem. You can even monitor the grill’s performance through the iGrill app, which is linked to the grill’s built-in thermometer.

Napoleon’s grates are made of 7.5mm stainless steel. Since they are a bit thicker than the Genesis II S-435’s grates, the food may stick to the steel. To avoid this, make sure that you lubricate the material properly with some oil.

The Napoleon Prestige 500 RSIB also has a thin warming rack, which could get damaged if left in place for too long while using the rotisserie rear burner or infrared burner. Make sure that you remove the warming rack when using the infrared burner or rotisserie rear burner.

Build Quality

Both the Weber Genesis II S-435 and the Napoleon Prestige 500 RSIB have top-notch build quality.

The Weber Genesis II S-435 offers an unparalleled build quality compared to other old-fashioned grilling units. With its sturdy materials, the grill is built to last and won’t get damaged for many years. The Genesis II S-435 has porcelain-enameled gratings and lid which means the grill can maintain high levels of heat and is easy to clean. All in all, the grill is hard-wearing inside and out.

The Napoleon Prestige 500 RSIB’s overall build quality is also comparatively great. Thanks to its superior 304 stainless steel, the grill is sturdy and can survive many years of usage. It has a double-layered stainless lid that helps enhance its heat retention capacity. The grill grate is thick and durable.

The Weber Genesis II S-435 is a cart-style grill that is ideal to use outdoors. It has two swivel casters and two durable back wheels that make it easy to transfer. This Genesis II S-435 also has two metal tables on the sides for additional workspace and storage. With stunning stainless steel construction, the grill looks sleek and elegant. The Weber Genesis II S-435 is available in stainless steel and black finishes.

The Napoleon Prestige 500 RSIB also has a long-wearing stainless steel construction, which makes it just as sleek as the Weber Genesis II S-435. The Prestige 500 RSIB is also a cart-style model, which makes it easy to move and use outside. One of my favorite features is the NIGHT LIGHT™ knobs that illuminate in the dark. With these safety lights, you don’t have to worry about leaving the gas on.


Weber and Napoleon both offer an extended warranty period for their products, but there are key differences in the way the two brands grant the warranty.

From the original date of purchase, Weber provides a 10-year warranty on all the parts of the grill. These include the burners, grill grates, grease management system, lid, and more. Note that normal wear is excluded from the warranty. Only the original buyer of the grill can take advantage of the warranty.

Napoleon grills come with a unique warranty package, as selected parts of the grill have a lifetime warranty. These include the cover, cooking grids, aluminum castings, and stainless steel base. The gas burners and cooking grids have a 10-year warranty, while the infrared and rotisserie rear burner have a 5-year warranty. It’s a complex system, but the lifetime warranty is surely worth it.
