Can you borrow the Giant and see how you like it? I went for a used bike at first. Since I was starting from scratch, with no idea what I wanted from a bike, I decided to spend as little as possible, and go from there. I ended up loving riding so much I was able to justify a really nice new bike 2 years later. But, I wouldn't have been able to choose that bike without the help of my old bike.
Edit, I missed the part about you riding for years. I think you should test ride the Giant, and the Dolce. You'll know which feels better.
