I have 20's P40 and to be honest with you I am not an expert or anything but I don't feel the lose in performance. I use my stock 19's sometimes and the only differences are handling (it could be be the tiers) and it is more comfy with the 19's. It is all up to you, what do you prefer?
hope it helps.
