At this point im rooting only for the hotspot tether (which works). other than that, until these knox bugs get worked out, it's really not worth it. if sprint wants to charge me a buttload of money every month, you better believe im gonna get that money's worth!
Also, qbking77 has a youtube video that will root all variants of the note 3. I used that one and no issues until knox got involved. super easy too. took about 2 minutes. qbking77 also has a video for the hotspot tether (or go to his website).
