I agree with Chris that the canister-top burners absolutely must have a folding 3 legged canister base. I have three of these and finally found one that fits any size base securely. It’s a matter of safety, as he mentions.
And that is the key word, “securely”. Some of these folding bases wither won’t fit all canister base sizes or they won’t stay tight on the canister.
My own canister-top stove is a folding Brunton Crux. It is slightly heavier than the Pocket Rocket 1 or 2 but works very well with a fairly wide flame pattern.
