The components on bikes in that pricerange will be very similar. In fact, the Aggressor and Timberline have the EXACT same components.
First, decide whether you want 26" or 29" wheels. Your riding style, terrain you ride the most, bike-feel preference, and your height all play a role. The Aggressor and Trail X2 are 26", and the Timberline is 29". Then go and test ride them, see what fits and feels best, because the geometry on all the bikes will be slightly different. The bike that feels best is the best choice.
