Webers have a more efficient heat chamber than most other grills. The vent is at the bottom, not the top. That makes everything feel much more heavy, which pisses many consumers off. There are other facets of the design that help out as well, but that's the one that's easiest to understand.
The Genesis chamber doesn't even have a bottom. It doesn't need one. It took other manufacturers a very long time to get that far.
Everything just falls straight through to the drip tray, which is heavy enough by itself to kill someone if you so decide. If you want to go big, you really need to go charcoal or spend a fortune.
There are plenty of nice grills out there, but unless you need something with a larger grilling surface, you can only get one that's as good as the Weber, not better. Even the big ones, though, can't actually be better. They are just bigger. There are only so many ways to get a skinny cat. Once you reach a certain point, a part cannot be improved within reason.
When I come across a grill that's as good at cooking, often it turns out to be flimsy. If it's flimsy, I consider it inferior. If the sides and bottom of the heat chamber are prone to corrosion, I likewise consider it inferior.
You must understand, I'll take a new brand new bolt and have it blasted, polished, and plated the way I want. I explore design down to the absolute finest detail.
If I consider something inferior, it could be due to something as small as a bit too much flex at a joint, the way a hinge is designed, or the metal a spring is made from. I'm a bigger pain in the ass than James Dyson. I put Teflon slides on my drip tray.
Just because I don't like something doesn't mean you won't.
