I bought a Tavor last month ... for the positives;
It ate every type of ammo I tried in it from dirty underpowered Tula to the decent Russian Silver Bear 62 grain HPBT, and very decent 62 grain Carl Gustoff and lastly Federal M855 green tips; also it has decent (although very tall) back-up iron sights on the factory rail.
Negatives; I've never been so disappointed in a gun purchase that had everybody raving about it in my life. It has the worst trigger I've ever pulled and the fact that it's a bullpup has nothing to do with it; I've got an AUG, an M17S, a PS90, and a Valmet M82 and the Tavor is by far the worst; but at least you can buy an aftermarket trigger for about $340+ to remedy that ... Then there is the issue of the LOP if you're 6'4" it's not a problem but most people don't have arms that long. Most guns have a LOP OF 12-13" to fit the average male but the Tavor has a 16" LOP makes it not only awkward but poorly balanced too ... add to the other negatives, most optics for modern weapons are built on a standard height fit for the AR but that's too low for the Tavor because there is no drop in the comb/stock which means using a riser or buying a taller aftermarket rail (there are several aftermarket rails to choose from). So to make it, what most Americans consider "shootable" you have to spend another $500 after you buy the gun! The only way you could make this gun worse is to SBR it ... I hope I didn't hurt anyone's feelings, that's my opinion of the gun.
So to cheer myself up I bought a Bushmaster ACR ... Mostly because I'm not a fan of the SCAR; the flimsy stock and reciprocating charge handle that is just perfect for whacking the the heck out of the thumb of left hand if it slips up too high ... which will also cause a FTF.
When the ACR was introduced as the Masada by MagPul I was really excited and then disappointed when it didn't materialize but then Busmaster picked it up. It was a bit of a roller-coaster ride on this gun and I'd hoped that would pull Bushmaster out of the funk they'd been in ... it didn't, then Remington/Cerberus bought them out ... Anyway, as it evolved the only difference between the Basic and the Enhanced is the hand guard. Basic is a smooth MagPul design and the Enhanced is covered in rails (which I don't care for).
Negatives for this gun are the back-up sights are the plastic MagPul sights ... and the ambidextrous safety selector is just long enough to poke your trigger finger, and lastly it's about 8 pounds unloaded (but so is the Tavor)
Pluses are the quick-change barrel (I'm looking forward to a 300B.O.), non-reciprocating charge handle that can also be used as a forward assist if necessary, some AR compatibility such as rail height and trigger components, a much sturdier folding stock.
I found a brand new Basic model and got a good deal on it ... Several owners have and like them and they got good reviews on the M.A.C. Channel so, what the heck ... Now I'm the proud owner of one.
This is probably a stock photo but I haven't picked it up yet.
