Tavor all the way i think of the Tavor like the better more user friendly Aug. You have to remember the Aug is old it was developed during cold war era. I'm not hating the Aug it was well past anything at its time. With the Aug you can get a butt stock that will accept ar-15 mags but won't lock open on last shot. when your shooting off hand (left) with the Aug be prepared for a mouth full of hot brass. The tavor on the other hand fixes all those problems. Also the weight of the tavor is more in the back so it doesn't tire you as fast when your holding it. Also you can completely change the tavor for a lefty shooter just needs a lefty bolt. Its up you if it was me id choose tavor then I'd get an aug later on. Hope it helps a bit sorry for any typos and errors typed this on my phone.
