I have climbed with SummitClimb on three expeditions now (Cho Oyu, Everest and Dhaulagiri) and I can safely say that I love them. Basically what I find the main difference being that the top end companies hold your hand far too much. With Summit, you can climb on your own or if you dont feel comfortable, with someone else. Obviously the ability to climb alone will depend on your own ability, confidence and level or expertise etc. As it says on the website, summitclimb is set up for climbers more then novices although to go with them as a novice is no problem at all either. But generally speaking with Summit a lot of the expedition members have a good mountaineering knowledge allowing also to that freedom of movement. At least that is my experience with them.
