I have both X95 and TAVOR, in the military world, they are the most prolific bullpup weapon system so it is good to know how to use them.
I don't see anything wrong with the original TAVOR. It has a more angled pistol grip and a longer LOP so the mass seems to sit more to the rear. The ergonomic is more geared towards the regular shooting position in military qualification down at the prone. If you are a big guy with a bigger hand, and shoot in more traditional position the TAVOR is probably more fitting.
The X95 was originally called the micro-TAVOR back in the days, which was a result of input from the assaulters. If you look at what assaulters do versus what the regular grunts do at qualification, there are certainly differences. Hence the micro got a straighter pistol grip ( the same reason BCM, HK416, and magpul make straight pistol grips for AR15) because it is more conductive for faster trigger work. The shorter LOP, the round handguard and the relocated charging handle are all for that kind of work.
I understand the X95 charging handle is in the way, but the Israelis tend to use grip lower on vertical grips and have their light mounted low, so it is not an issue for them. You can put the handle on the right side, it is actually easier to clear type 2 malfunction with this arrangement.
Accuracy wise, in all practicalities they are similar. They are 300m Minute of a Person accurate and that is pretty much it. I don't tend to analyze it too much. All in all, they are effective and reliable weapons.
