I see a potentially big difference, the seat tube angle. While I think they are both too steep, a 74 is really steep. I wouldn't even ride a pure racing bike with a 74 deg. STA, but that's me. If you've ridden on a bike before with that STA, fine, but if not, you may not be able to get the seat back far enough. You gotta know know what works for you.

Too many manufacturer's are stuck in steep STA's . Still ...... after all these years.
