No redundancy for motors / ESCs / props, flight controller (possible exceptions for gyro's and acc's that may be redundant), battery,.. means over a dozen single points of catastrophic failure. So no, not very reliable in any absolute sense. Someone mentioned 94 flights with no problems; lets say that is 94 x ~17 minutes or ~28 hours. Imagine declaring your car reliable because you hadnt had a single failure all week!
Compared to other brands or types; not enough data to say anything meaningful. Probably not better or worse than the competition, but the point Im trying to make is, these things are by their very nature unreliable and they do crash.
