There are benefits to the bullpup system and the little I've shot the Tavor it seemed like a good enough rifle. That said, I didn't torture it or run it through a high round count.
Personally, I'm not a bullpup person and wouldn't pay $1700 for one. At $700-$800 I'd grab one to play around but I don't think I could have the confidence in it that I do in a base model Colt LE 6920 to use the rifle for anything serious. If it's relegated to a range toy status (in my mind it is, use it how you please), I have troubles justifying $1700 for that purpose.
When I match it up to a no frills 16" AR, they are equal in barrel length, the Tavor is heavier by a pound to a pound and a half, and the Tavor is shorter by about 6 inches overall. If it were the same or less weight, it would be great as a hiking/hunting/bug out/etc rifle. But it's heavy and on my back 6 inches of effectively longer barrel length can be packed around but the extra pound and a half can't. Anymore with the Sig pistol brace being legal, I find it hard to not simply buy a 10.5" pistol, toss the brace on, and have a lighter and smaller package than the Tavor as well as parts availability with the most common domestic rifle built today.
I'm not trying to say the AR is the only good option, but I think it's a better option than the Tavor. The biggest benefit I see from the Tavor is that it is easy to use in a vehicle while still giving you 16" barrel length velocity. That's a situation I won't be using short of the Russians invading. Other than that, if I'm in a spot tight enough to need a sub 30" rifle, a pistol/SBR AR is going to be lighter, potentially more compact, and have parts available for the next 50-100 years, and will still be well within the effective range of the round. Most any situation I can see that I need 16" of barrel length velocity, I'd rather the extra 5-10" (depending on hand guard) of grip distance to stabilize the rifle, though I've never been a fan of both hands being close together.
If you want to buy a bullpup rather than a pistol AR, the Tavor seems like a quality rifle. It's parts availability makes me nervous and would push me towards someone like Steyr AUG simply because they've been doing it a long time, though it too isn't a light rifle for the compact size. I'd have to do a bit more research on either, their distributors, and their track record for supplying parts though before I made any $1700 choice.
