I was going to say Primo Oval as well - it's in a category of its own due to the shape. I use mine multiple times a week and the shape makes it really versatile. True 2 zone grilling, a large amount of usable space when using the whole charcoal basket as a grill or smoker, added real estate using the 2nd tier raised racks. All of those things allow me to use it in a way that I could not with any of the other kamados I owned (BGE, Akorn, Vision) so for me that provides a lot of "value" - they're not cheap though.
From the standard round kamado perspective, I'd say an Akorn or a Vision (especially if you can get one on sale end of year for $200ish). The warranty is a differentiator between them, but I found the Vision to be of good quality and I got it on sale at Sam's for a couple hundred bucks. Akorns are good little grills, they're extremely well insulated and that makes them very efficient. They're priced commensurate with their build quality and longevity, IMO. Eventually they'll probably rust out or start to show their age and you might have to buy a new one but if kept covered I don't see why you couldn't get 3-5 years of regular use.
