They both seem good picks, and chosing a hybrid bike makes sense. Buying a new bike from the local bike shop (LBS) can be an emotional experience. The limiting factor is always the price. Generally, the more you spend on a bike, the better the components will be and the lighter it will be. Ask about free tune-ups and adjustments for fitting. Sometimes, you can get a deal with accessories such as a helmet, lock, and lights at the time of purchase.
I believe Giant is the biggest bike manufacturer in the world, as they supply frames to many other bike makes.
