any issues on 681 like getting hot, unstable etc?
It's strange you're not getting the OTA update to .757...
The best way is to see for yourself, try it out and if you don't like it, use Flashtool (or PC Companion?) to downgrade.
I personally like .681 because of Kitkat
There was a few issues on my device (Xperia Z1), such as unable to change the lockscreen wallpaper, but that was fixed by fresh-installing the firmware, not upgrading. As for performance, that's device specific. On my Z1 it runs pretty good except for random lag on the home screen, but I corrected this by using a different Home launcher. My phone did get a tad bit hotter with my .681, but hardly noticeable.
.681 is pretty stable IMO, I recommend trying it. But again, it's solely based on opinions.
