Be sure to hold both versions if you haven't to get a feel for what works for you.
I wanted a SAR when they came out but never got a chance to buy one, then after the X95 came out I was able to snag one of the first few in OK (after all it was supposed to be "better" but I'd never held one). I almost immediately regretted getting the X95 over the SAR, partially because of the accuracy (1.75-2" at 50 yards with 6x scope were my best groups, with good ammo, rest, etc), but mostly because the SAR mag release and layout actually works better for me (but I shoot lefty for eye dominance). I was constantly reaching for the SAR mag release location on my X95, but I'd never shot a SAR (or any bullpup for that matter), it's just naturally how I want to reload a bullpup I guess.
I ended up selling the X95 after a while and haven't replaced it yet. The Kel Tec RDB seems to fit my needs better being downward ejection and less gassy suppressed, but I'd also like a SAR. If I had the funds I'd have both! From what little I've seen there are some deals to be had on used SAR's with upgrades.
