I don't consider the X95 to be a product improvement over the Tavor ... Just another variation.
I prefer the Tavor over the X95 and if you watch most of the big YouTube reviewers no one is dumping their Tavors in favor of the X95.
It's not that the X95 is not accurate, quite the contrary - it is - BUT ... It does not shoot accurately
consistently.... 1+ MOA groups one set and 3-4 MOA groups the next...that is not what I am wanting in a $1800 rifle...
My Tavor shoots consistent groups as long as I do my part...and I actually prefer the mag release of the Tavor over the 95..it simply works...
As far as the AUG - go OEM on mags.... Steyr waffle mags are far superior to AR style and giving up the bolt release on the AUG is a mistake... You can find the factory mags on sale often ....and Magpul has just released their own AUG mags if you want to save a few dollars.
If you need a rifle that has an AR style mag release, that uses AR mags, with an AR type trigger - save a lot of anguish and get an AR...
Between the 2 (Tavor/AUG) - I think I would choose the Tavor simply because I like the long stroke gas system - and AK inspired bolt.
The marketplace is full of add ons and the Tavor has an affordable caliber conversion....
Tavor balances better than the AUG but the AUG feels more "solid"....when shouldered.
I own and shoot both...
