I don't know about some of the others, but I have a Kamado Joe and I would get it just for the warranty. Lifetime on the ceramics. Mine is 10 years old and the base got a hairline crack. I submitted the claim and because they only make red now, (mine is black0, they sent me a brand new red dome as well. It took about 6-8 weeks but this was in the spring and covid was ramping up so I was ok with the wait. I'm still cooking on my black one and have the new dome/base waiting until the crack in mines gets to where it's not usable.
