I have to go with Lindsey with Mick second. One thing in Lindsey's favor is he has a solo career. I hear Trouble often at my retail job. Mick doesn't have that solo career - his career IS Fleetwood Mac. However when FM isn't doing anything, Lindsey is doing stuff like touring, putting out albums, etc. Also, the whole SNL thing adds to his fame.
...plus Lindsey's wikipedia page is longer than Mick's!
