I have pretty much all the Waves stuff but I find I'm using the F6 a lot these days.

Regarding the piano roll, I thought it would be more useful than it actually turned out. I'm finding dynamic EQ far more of a feature, especially when teamed with the RTA.
Just look up the frequency of a particular note on the odd occasion you need it.
