Honestly? I have PP, and I thought I'd never need Bare Canvas paint. However, after getting and using Bare Canvas paint, I can honestly say I need it. PP is just disappointing in comparison.
I've still got the PP, but I just use it on the lower lashline if I'm applying any e/s there. PP is good for that, which is a relief, since I'd hate to just let it rot in my bathroom cabinet, after all the damn effort it took to get one (it's always sold out).
