Which Root Method

Im coming from a rooted Verizon Galaxy S5 with safestrap, Im no stranger to root methods and installing custom roms. With that being said Im getting the Verizon Note 4 and have been reading and have information overload as some of the information seems old. Im just looking to root to install Titanium Back up and possibly install a stock debloated rom. I'm still on KK 4.4.

What is currently the best root method and are there any stock roms for the retail version.
Thanks for any help
