Momentum has really nice hotel rooms, with a full kitchen, a tv, a pool, and a tramp in the back
I'm not sure who CoC's coaches are but in my experience Momentum's are great, they genuinlly care about you and your performance such as watching film and doing the trick your trying to do as opposed to something they would rather try  they also give each group a new coach everyday unlike other camps
They also have a private t bar as opposed to CoC
Momentum also has great and innovative terrain, such as their jumps, the wallride, and their rails
Their rails are also dope, up rail, one with a gap in it, one that kicks you, flat downs, double kinks, and more simply put g star raw
Momentum also has really great afternoon activituies such as:  climbing, biking, waterramping, an assortment of sports, sky lining, skatepark, wakeboarding and an assortment of other things i cant think of
Momentum also is skiers only
So
If I were you I would go to momentum but I want you to go to CoC so Momentum is less crowded
I have been to Momentum for the previous two years so if you have an questions feel free to pm me
