Which one to get rid of?

[Mr. 16 gauge]

I have to military-style rifles: an AR15 (Bushmaster) and a M-14 copy (Chicom-Polytech). I've decided to thin out what I have, and will probably get rid of one of these rifles; the question is: Which one?
I bought the M14 first, have taken deer with it, and have a few odds and ends for it (scope mount, extra stock, several high capacity magazines).
I bought the AR15 with the idea of using it as a varmint rifle and a SHTF gun. I have a scope mounted on it, as well as several high capacity magazines as well. It is a post ban gun, so it doesn't have the flash hider, bayonet lug, ect.

I bought both these rifles with the idea of using them as hunting guns first and SHTF guns second. Living in the suburbs of Detroit has it's disadvantages

So, if you had to decide between the two, which would you keep, and which would you get rid of? I reload for both; the Chicom is finicky about what it likes; the AR not so much.

BTW: I don't need to sell the gun, i.e. it's not like I need the cash to pay the mortgage, or the kids tuition....it's just that I don't have the time to shoot anymore as much as I would like. I will most likely keep all the shotguns (since I consider myself primarily a bird hunter), but I have a few handguns in the safe that I will put on the block because I just don't shoot them that often.
