I think he meant "OS" rather than "ROM". The reason he posted in this thread only indicates that he already tried the rest and posted on the best....
As for OS options, we all know that we can't make everyone happy all of the time! Just as Apple has been loosing ground to Google by leaps and bounds, today's headline:

Good luck.
