I can't imagine carting M60s from dorm room to dorm room for 4-5 years. The high probability of your gear getting stolen by thieves or damaged by roommates would be another factor for me.

Brass on my M60s sounds excellent. Only loud, strident trumpets have come close to annoying, but to be fair - they eventually become annoying to me in person. Miles Davis' CD "Love Songs" is incredible on my Axioms.
