Yeah Snaps (and performance too) are not really Ubuntus stopper problems (you can easily remove them). I mainly want Plasma 6 fast (as I am sure an en par Cosmic will need at least 2 years) so Kubuntu is not an option really. Also snappifying core packages like Firefox, where I am not sure how that affects the tab isolation capabilities, is a bit annoying.

But Ubuntu is pretty quick!
