Map, check out Talking Heads 'Big Business/I Zimbra' live 1983 on YouTube if you've not already.
Classic David Byrne at his best!

Kind of surprised that Ann Wilson hasn’t been mentioned. But, I kinda hafta agree with the Chrissie Hynde vote. No Chrissie, no Pretenders. 

I didn’t say Collins over Gabriel.   Only that Gabriel was replaced and the group went on to even greater fame works against Gabriel as Genesis MVP.  MVPs are not easily replaced.  
In fact when Collins left and they gave Ray Wilson, a fine vocalist on his own right, a go, that was it for Genesis. 
So there is a case to be made for Phil Collins as an MVP with Genesis. 

Paul Rodgers, in the "Talent" division; Bruce Springsteen, in the "Frontman" category; maybe Bruce Dickinson, in the "Both"
