...a next level battle proven bullpup platform in non-restricted.
Non-restricted true, battle proven? Not true. XCR was designed for SOCOM to compete in the SCAR competition, the Tavor was designed to save Israeli industry, was employed by a small amount of units in the IOF, and is now widely being replaced by the next "next level bullpup". The tavor was never used in any real "battle" is not even widely employed in the the IOF, and is already being replaced.
...and to be well and above the finest bullpup deign yet fielded; and I generally hate bullpups.
You hate bullpups, but you love the Tavor because it's magic, not a bullpup?
I like the XCR/SCAR, but to me it just has that AR feel, which is not bad, but not exciting. IMO, its only real appeal over a high end AR is the non-restricted classification.
What is an AR feel? The XCR uses a Kalashnikov type gas operated action with a long-stroke gas piston attached to the bolt carrier group; or do you mean it looks/feels kinda like an AR lower?
The XCR is multi-caliber. It can make accurate shots at range, be used in a wide variety of roles including hunting etc as you can take it out to play, suited to shouldering on either shoulder, and was designed for use by arguably the most experienced, well trained soldiers on the planet.
The Tavor has rifle length velocity in a carbine length package, and is suited for kicking in doors so long as you don't have to clear from the left of cover much, and for those who are small and weak and the non adjustable ergos work for you.
So if you're kicking in doors, or standing behind the bench making holes in paper at short range, and if fits well the Tavor is better.
If you're looking to do anything else, the XCR is win.
The only reason I can see these two being compared so often is they are both non-restricted for now. Really, on nearly every other level, they are apples and oranges.
