I had never owned a gas grill until about a few months ago. I did a ton of research and the brand that stood out to me as the best in terms of reviews on quality and durability was Weber. They build a variety of gas grills that vary in size depending on your needs. I needed something big enough for a small family, so I ended up getting the Weber Genesis II E-210.
When you turn on the grill and get down to it, you feel like you're using a top of the line product. The build quality and ease of use are the most obvious pros of the grill - it's like the simple reliable cast iron pan everyone needs in their kitchen. It's on the high end of the spectrum in terms of price (~$499), but it's easily justified by the solid build quality. This is a product I'm certain will last for years.
