I have thick set, full lips, so for me cup width is not a big deal (I play all trombones, except alto, and double on trumpet), but rim shape does affect me. I feel most comfortable with thin, rounded rims. Flat rims, or rims with sharp shoulders are uncomfortable.

Same exact feeling! Thick full lips, slightly less thick than average rounded rims over here too! Doug, is this preference common for people who have thick lips?

If they are the particular embouchure type that Reinhardt called IIIB, which I describe as Medium-high placement, and play with a noticeably downward horn angle. That puts mouthpiece pressure onto the inner and outer edges of the rim instead of the face of the rim. Therefore, rounder feels better.

But lips like that do not necessarily mean you are that embouchure type. Type is defined by function, not appearance (of the lips). I use appearance (placement and angle) as a description because that's something you can easily observe.
