I know nothing about the 230 except they have the 250C30.
I have however 1000 hrs in the 222U model. In the temperatures where we did operate them we had plenty of power in ISA conditions both with twin engine and OEI (training).
The LTS 750 is a good engine, very reliable now and cheap to operate and uses about 270 lbs/hr
pr/engine in the B-222.
The 750 engine is 735 hp at 2.5 min rating which means you loose only about 26% of available engine power in case of OEI.
We always had trouble doing engine topping test in it because we had to load it so heavy to keep her from hovering on one engine.
I was once told that the C30 in the B-230 is actually a smaller engine than the LTS101-750!
The B-222A model only has the Lycoming LTS101-650 engine which was too small for the aircraft.
The Sperry 4 axis autopilot in the B-222 is very good except in autohover since it does not have standard a doppler radar but uses accelerometers.
