Ok I actually do own and love both and although my wife would probably chop my d!ck off I would only keep the ACR and sell the tavor.
If you were to ask her this question she'd say sell the ACR keep the tavor.
Out of all my guns the Tavor is actually the ONLY rifle she loves to shoot and keeps on wanting to shoot. That says a lot, women are very picky.
That being said I'll never sell my Tavor anyways so, like never, ever...
You never know, the aliens might come, and Ill need her to shoot a rifle...
