it's not the damage that draws me towards f12 it's the timing, online you can miss time your njk and lose advantage frames but with f12 you know you're always in the money if you hit it. Also I've tested out f12 ender vs reptile's ex slide, it's completely safe.I've always really preferred NJK for everyone, more control over spacing, guarantees wake ups can't touch you even if you miss a few frames, makes Clones safe that F12 doesn't (like say Reptiles), and the plus frames are never wasted considering you are almost always following it up with another attsck so it also helps your Oki and gives you a better chance of armor breaking if you misread.
Just my opinion, many prefer F12 for there extra point of damage.
