Mostly, I think you'll have to just get used to it. There are some customization options, mostly in regards to what happens when click or double-clicking a clip, but as far as the PRV itself, once you get used to how the smart grid and smart tool works, and remember to set the new note length to "last touched", it really works pretty well. Sometimes the controllers can get a little cluttered, but I've not had any difficulties getting what I want into the track quickly.
I will say that I went from Sonar 5 to X1, then X3e and now Platinum, so I have had a good while to unlearn old muscle memory movements and learn new ones.
