Seems to me 44S is still the most stable. I'm still on 44, been wanting to upgrade to L but keep reading that many users encounter prob and batt life not as good
I would advise you not to upgrade...
Touch sensitivity is really terrible for my TPK touchpanel OPO from mid Jan 2015... on CM12S, 12.1, 12 and Oxygen. They all run different touchscreen drivers and at least in my experience, none of them have nailed it.
When flashed Oxygen, it was fine at the beginning though battery drain was massive and the phone was either warm or hot at all times. I wanted to skip CM all around but the thing was that I couldn't stay with Oxygen
(buttery smooth performance but terrible touchscreen, google play wakelock and power management)
When I was at CM12S, it was just as bad and I went to CM12.1 nightly. Wasn't as bad but the touch speed was really poor still.
Went back to CM11S 44S in the end (38R had the best battery for me, but 44S was the most balanced one in usability and battery life)...
Might wanna check if you have a wintek or TPK panel though though most of us will have a TPK. Mine works best on 44S so far...
