What speed to you ride at? Do you like to take in the scenery or are you trying to get a little fitness on the bike?

I, personally, don't see any value in a front shock on a non-mtb... but there's obviously a market for them. I think they are gimmicky for a hybrid, advertised as some sort of upgrade when they really don't add anything. While I'm not 100% opposed to a suspension fork, and I may even consider using one in a personal build... there's a big difference between buying a $200 suspension fork after market and buying a $400-600 bike with what amounts to a <$100 suspension fork.

You may find yourself growing out of the Adventure... that's less likely with the Quick. Quick will probably have higher resale value too.
