My guess would be Phoenix. I'm using it for some days now and it runs great. All the planes I have in real are also in the sim ( Extra, Ultimate, trainer ...) and they feel like just the real thing. Cost me about 130€.
No problems installing it. Even the connection and calibration with my FC-16 went very easy.
I would recommend it to everybody.
I have never used G3 but if you asked me which is the best for the least money, every one will agree its Phoenix. It only costs half of G3.
Good luck
