well, all I can say is I bought a Giant faced with a similar dilema last year. I went more road/touring but I love my bike. Giants are great bikes as they are the worlds largest frame maker, so everything basically fits right up. Take them each for a ride around the block and pick which one you like best. Don't worry about what the guy at the shop says unless it's recall information. Pick whichever one you feel most comfortable and ultimately makes you most happy.
