Despite the fact that the h2 and the tlr 22 dont have servo savers, newer servos can take a massive punishment,
I have the 22 and it is a tank, its very difficult to break parts, I've seen sv2s break things from a gentle tap with a barrier,
I think if you are making mistakes/new the 22 is the best option out there, if you are a confident driver, probably the sv2,
just my 2 pence
