TAVOR and X95 have the same "guts", just different shells.
The thing that really affects civilian user is the LOP. Bigger guys my need find the original TAVOR more comfortable. People who use traditional scopes, or employ lots of more traditional shooting stances and positions may want to have longer LOP. The location of the charging handle on the TAVOR is also better for people with scope. ( won't wreck knuckles). I am a small guy, I actually don't mind the longer TAVOR LOP in my typical normal attire.
The X95 is infinitely better if there is a need to attach light and laser, simply of the relocation of the charging handle. This is way more important for military application.
Both magazine releases are workable. I am actually quite fond of the TAVOR lever release, but it cannot be transplanted to the X95. The X95 has a shorter distance between magwell and pistol grip, it doesn't have enough space for a lever release.
