Again I think it may depend which country we're taking about.
I think Mick would be the most recognised here in the UK, his Brit Award appearance is dragged up every year for a start
I would say (in the UK)
1. Mick
2. Stevie
and then any from Peter, Chris and Lindsey.
I've talked with family members/workmates who aren't that familiar with the band and the one they always know is Mick.
