Allow me to chime in here. I have just a bit of experience with the Big Green Egg, the Weber 22" Kettle, the Weber Smoky Mountain, and a Weber propane.
First I find it more than a bit hypocritical for anyone on this forum, of all places, to denounce the BGE for its price. I guess if that's your reason for knocking it down you should sell your Festools and save some money and pickup DeWalt, Makita, etc.
I paid $400 4 years ago for my Weber propane. Fast forward to today and the original grate is gone, rusted through. The flavorizer bars need replaced, rusted through. The outside is in need of love. The door is rusted. I don't enjoy using it but it's a necessary evil when I need something cooked in under 20 minutes.
I branched out to the Weber kettle a year after the propane. I fought with it for two years maintaining 225-275 for cooking ribs, pork butt, you name it I probably tried it. Raining? Forget about it. Cold? Nope. And you have to use a water pan that acts as a grease catcher. Have fun disposing of that after every cook.
I now own a large Big Green Egg along with the kettle and propane. The kettle is dedicated to rotisserie duty which it excels at. If I have the choice I cook on the Big Green Egg. I've regretted a lot of purchases over the years but this is not one of them. And if it breaks in 10 years guess what, I won't spend any money. Lifetime warranty. Over the past two weeks I cooked a 12lb packer brisket on it maintaining 275 for 10 hours without adding any lump charcoal or really doing anything and a 7lb pork butt at 250 with the same experience. Because it has very little airflow during long cooks the food stays more moist and you don't need to mess with a water pan.
For steaks I don't do high heat until the end. Reverse sear is the only way to go. Buy 1" thick well marbled ribeyes and cook them 225 until they're near desired temp. Then open the vents and let the egg get up to 600 or more and sear it for ~30s per side. If you haven't tried it this way you need to.
Like any tool you get what you pay for. It has a learning curve like anything else but I couldn't do without mine.
