Short version- as others have said, get a ceramic style egg cooker and don't look back. I would specifically get KJ if I were you.
Long version- A little over a year ago I decided I wanted an "egg" style cooker. I've owned and/or used just about every version of grill/smoker out there, and still own 4 different styles (Gas, KJ, Offset wood box smoker, propane/charcoal smoker) Did a lot of research and I found that Kamado Joe had the best features/value, especially if you can find it at a Costco roadshow. I purchased my KJ in May 2019 and it has not disappointed. I debated between a pellet fed (Rec-Tec RT-700) and a KJ Classic II. The reason I went with an egg style and specifically a KJ:
No technology! Simple- I didn't want my long cook, or any cook, fawked up if the power went out or a motherboard decided to fry. Nothing to ever go wrong on an KJ
Pellets- nothing against them, I use them all the time to smoke cheese, but they have their limits
High heat- you can't sear at 750+ degrees on many types of grills- no problem with ceramic grills
Versatility- as mentioned- you can cook at 225 for 16 hours (my longest thus far) without touching it, set it to 350 and bake, pizza at 350, 450, 550+ depends on crust but you can do it perfectly, grill at any temp, and sear at insane temps- perfect if you use sous vide, but that's another thread!
Longevity- tied to the first point, I plan on having my KJ for decades
KJ specific- split grill is really nice (divide and conquer is what KJ calls it), spring assisted lid is great, accessories- I've got their wok and pizza stone, highly recommend.
After I got my KJ, my gas grill was sitting unused. I found the perfect accessory for it- the little griddle. Holy hell, this converted my gas grill into a huge flat top. If you've never cooked on a flat top, you are in for a real treat. I cook 90% of our dinners either on the KJ or the flat top.
