For everything I've read, most people don't like the VVTI because its a little harder to tune. As long as you can find a good tuner near by its a much better motor. Get your torque at lower rpms, runs smoothing and much more fuel efficient.. Downfall is after market. If you want to stay south of 500hp not a problem got vvti, if you want a huge HP motor than got GTE. Either way great motors!!
