Depends on your use really.
I've cooked on a couple of stick burners. Love em, but they're a bit of work at least as far as fire maintenance goes.
Cabinet smokers are more of a "set and forget" mentality.
LOVE the CTO, but then you gotta have power. The built in thermo is KING though.
If you plan to cook a lot of meat, the Vault will hold more than the CTO. CTO has more temp variation from top to bottom than the vault, but less than the traditional offset. Of course, some folks like that variable temp throughout the cooker too for versatility.
Not played with a reverse offset like a Lang personally.
Again, depends on how much meat you plan to cook at once, portability, etc. They're all great for Q and as versatile as the cook wants to be.
Out of all that I have cooked on, I think I love the Jambo the most, which is a "traditional" offset. Awesome cooker.
