Where are you located? I have the same Whyte bike you are looking at. It is a big hitting bike. Downhill worthy bike. It is an extremely capable and stable bike and just wants to go fast. The steeper and faster, gnarlier the better. It is a very good climber though. Not fast but very stable and easy to maneuver around and or over obstacles. Might be more bike than you need or want though. It is more bike than the other two you have listed as choices. If you want heavy hitting Enduro, downhill capable bike the Whyte is the one to go with. If you want trail, all mountain/Enduro bike the other 2 are better choices. But if that's the case you can get a much better brand new bike for about 150 more.
There are lots of bike but it is tough to choose the best bike. We have to consider 3 major things when we choose a bike. 1. frame. 2. gears. 3. Brake. You can read the article to know more things. Mountain bike guide.
