I think the talk of ride quality in this thread is irrelevant, for a start the same bike may feel quite different to two riders depending on things like weight, fitness, technique and perhaps most importantly, body morphology. where you ride is also a consideration.
Personally when I hear Marin the image that pops into my head is a matte Zolatone Pine Mountain with fluoro orange forks/stem/bars, like this (don't know if this is a members bike - Google image search result)
That is a cool looking bike (and that should be the major consideration in this vote).
At the risk of losing some cool votes (but hopefully gaining some) here is my latest Marin (and my first for 5 years or so) currently in a brown van somewhere between Utah and Toronto. I think this is a very cool looking bike.
