Its not so much the performance difference its more the torsional rigidity which affects how the car handles.
Obviously some people don't care about stuff like that so much and claim they wouldn't know the difference anyway. I am one of these people, for example. But these.people would probably be better off with an E93 335i rather than a compromised precision instrument.
This is why the iconic M3 will always be a hard top.
