In my (admittedly short) experience with Fender 9050, they didn't feel much different to Ernie Ball Group flats. I've got two sets of Ernie Ball Group III on two basses, and to me, they feel and sound very good. I play with a lot of slides and small corrective movements, for those being fretless basses. It might feel different on a fretted one though. My only fretted bass is a Stingray strung with Cobalt flats.
I think it might also be about one's mind-set. Mine was "it will work whatever effort it needs".
P.S.: Dunlops are fine, but they also are bloody expensive. They feel a bit smoother though. Each to their own.
