When I knew that I wanted to buy a "zombie" rifle; I considered buying an AR for only a few minutes. I bought a mini 14 and never looked back.
I'm not much for accessorizing a gun once I get it and, for me, it was also about aesthetics. I like the look of the mini
The guy I bought it off of bought it new and had only put a hundred rounds or so through it. He told me he was "just an AR guy". I was good with that.
Too many of each type out there for one to be superior over the other. Like one of the above posters said, get what you want. Whatever your choice, I'm sure you'll be happy.
