Reliable, generally.
Efficient?! Nope! 70% of the energy is wasted in heat and noise and, of course, pushing a piston up and down, having to reverse its direction on every stroke!
At least the Wankel Rotary Engine tried to improve matters, which it did somewhat, but they had their own issues, hence never became mass market.
