rkerider

I've been riding cheap Schwinn mtn bike with semi slick tires and really been enjoying riding and commuting but didn't want to spend alot at first to "test the water". I now want better quality bike, but can't decide between 2009 Trek 7.3FX or 2010 Giant Escape 2 City. I've test ridden Trek at LBS which was 20" frame and I've found one on CL for $400 local. The Giant has full fenders and rack for price of $525 at LBS. I've ridden both but can't decide which would be better in long run. I've been comparing componets and prices, but is one brand better than another? Is it more worthwhile to spend $125 extra to get bike that has fenders and rack?

Thanks
