I own three paints and only one paint pot, but I must say I like both - I have no problems with the staying power of either paints or paint pots, and while you get more product in the paints, I go through one tube of Bare Canvas much faster than one pot of Painterly, even though I use both daily. Painterly is much more opaque, I need less of it.
I get better colour payoff from my eyeshadows over Painterly than Bare Canvas, but on the other hand Painterly can make my eyelids look a little crepey and cakey with eyeshadow on top, and Bare Canvas never does that.
I liked the old colour range of the paints better than the paint pots. I'd like to have more paint pots, but none of the colours are must-haves for me except for Stray Grey, which was never available here, of course - I don't understand why they didn't make a great, basic colour like that part of the permanent collection. There are two or three more paint colours that I really want, though, more than I want any of the current paint pots.
