[Q] Unlocked bootloader and S-off, help topic

First of all, sorry my bad english.
I've unlocked the Bootloader and the phone is S-Off but before i did that, the phone couldn't receive any update from AT&T, android version is 4.3
I installed a custom recovery but i want to know what ROM do you guys recommend me, i'm looking for something with kit kat 4.4.3 or 4.4.2, idk what version is available to the cell.
Somebody can help me with it? or returning back to stock , i tried looking for a RUU for my phone but no results.
