I started off using the CC ESC gov on my 700E. It did okay, but I found I couldn't get it setup to eliminate tail step out on pitch pumps. Recently switched to a phase sensor and the ikon gov and I like it quite a bit better. I haven't put too much tuning effort into it yet, but defaults were better than CC ESC gov. There is the slightest step out still, but it is much better behaved overall now using the ikon gov.
