Don't get stuck on brands. Each brand has a low end product and a high end product. Components determine what a bike is worth, not the name on the frame. Most riders name the drivetrain (the gears, front and rear derailleurs) as the heart of their bike. Sram makes some reliable components but Shimano is still the standard for drivetrains, but they have entry-level products and top-of-the-line products too. The bike you are considering has Shimano components but they are definitely entry-level. That's not to say that they're bad. They'll do great on the neighborhood bike trail, but would limit you in a competitive mountain bike race. This is just one of the things that separates a $700 bike from a $1,700 bike.
