I can imagine choppers with more channels will be more difficult to fly. The 3 channel is easy but still took some practise, and confidence, to fly through doorways.
My 3channel chopper (approx 15cm long) has crashed many times but nothing has broken. It included a set of spare blades but the chopper is very light and the blades are fairly solid. Some crashes have been from over 2metres.
As I improved there is less crashing.
My total flying time is about 2-3 hours so far. Each charge lasts about 20min (probably would only be 1min if non-stop) so plenty of time to enjoy.
I also disabled the "sparkly" LEDs - too childish and waste of power.
