You really should give 6.5 a go now, yes before it was crappy and buggy but you can get a solid custom ROM running perfectly. I kept on going back and forth testing latest 6.5 ROM's before and returned to 6.1 but now I would never go back to 6.1 as 6.5 is a lot more finger friendly and the visuals are stunning, but as they say each to their own.
