leupold vx3 vs mark2 t1

[aimlesswonder]

A buddy of mine has a practically new leupold mark 2 t1 he is willing to let go. He heard i was looking for a vx3 for around the same price i was willing to spend. Long story short is i dont know much about either of these products and was wondering how the optics (clearity/ contrast) compare on both of them. I hear great things about the new extended twilight lens on the vx3. So my question is would it be better to go with the vx3 or go with the mark2 t1.
