NexusHD2 Android Forum

I'm using NexusHD2-KitKat-CM11.0 V4.4 http://androidforum.tytung.com/nexushd2-kitkat-cm11-0-t230.html now.

I use HD2 only for phone call with
Call Recorder https://play.google.com/store/apps/details?id=com.skvalex.callrecorder. (NO web, NO game, NO music, NO video).

Sometimes it lag with V4.4.

• Should I stay with KitKat 4.4 or come back to GingerBread or JellyBean for my use (phone call with recorder 2 ways)?
  
• Can you recommend some ROMs?

Thanks all.
