Well I updated my phone to the newest stock (rooted) software (leak). I can say a few things about it.
1) the low audio issue with recording video seems to have really been fixed. Very good audio during playback
2) most other audio has been improved as well, music sounds a little clearer, as do phone calls
3) dont know if the issue with headphones & phone calls has been fixed yet. (mic & speakerphone related)
4) seems the 3G/4G/LTE is a little more solid and stable (more monitoring is needed to prove)
5) battery seems to drain a little less, im not dropping in percentage at work like before but really need more time for this
6) ping is lower was around 95 on average, now showing around 80 on average with multiple tests & sites
7) speeds seem the same (around 10-12down and 5-8up)

Overall phones seems a little smoother & snappier.
9) GPS - Nav seems to pickup instantly now. Even have my nav working indoors at my office (couldn't lock on from inside my office before.
I will update this statements if needed to better reflect my experience. If anyone else has updated, your input would be appreciated..
