Be honest with yourself, what kind of answer are you expecting to get here? It's a bit like going to the Manchester United headquarters and asking who's the best, Man United or Liverpool
Go on your own experiences and thoughts, and needs, track record is what it's all about. I made my decision nearly 3 years ago and I have yet to see anything that would entice me back in the slightest, but that's me, and you are you. Best of luck.
