I love IWI stuff so I am definitely biased. I have an X95 in 5.56, a Galil Ace in 7.62x39 and their newish optic ready 9mm pistol, the Masada. I did replace the triggers in the X95 and the Ace. X95 trigger replacement was not worth the price. ALG makes a version of the AKT for the Ace and that absolutely was worth it. Also replaced the handguard on the Ace with an MLOK model from RS Regulate. There is another company that makes them now too, for less. Forget who they are now.
People say the X95 is not as accurate as the Tavor...that may be true but I am not as accurate as either and neither is the cheap steel I shoot through it most of the time. I like my X95 a lot and when I let people shoot it, they are smiling when they hand it back to me.
I got my Ace in 7.62x39 because it is about the best factory AK in that chamber around. Recently suppressed I shot some subsonic 196gr Brown Bear through it. The pings on a steel target from 100 yards are arguably louder than what you hear when you pull the trigger. Normally I shoot based on price per round so I like lots of cheap Russian steel for the most part. This is steel and Russian, but its about 50 cents a round which is not cheap to me. But it will be hard to go back to full speed cheap from the subsonic.
Masada is an impressive gun at its price point. I think I paid $500 for a pistol with optic bundle. Especially considering IWI shit usually is not reasonably priced. Honestly it reminds me of an improved G19, at least out of the box from the factory. 3 dot sights and trigger are vastly superior to my factory gen3 G19. Ergonomics are subjective but I think Masada wins there too. Standard mag is 17 v 15, in favor of Masada as well. Also, the optics ready slide. This was my first pistol to mount an optic and I liked it more than I thought I would. One downside is there don't seem to be any threaded barrels for the Masada.
Never shot or handled a Scar.
