which ever one you prefer first. I use TWRP. Some use Philz, which is based on TWRP. From what I've read, it may be good idea to go with Philz over TWRP when and after converting to Android 4.3; something about TWRP not backing up or restoring correctly. Obviously there is still ClockWorkMod (CWM). I can't attest to it because I haven't used it in over two years.
