wildchild,
One way to decide AR vs Mini would be re-sale value (not that that is as important as function), as a guy did a
this thread. However, some of us just like the Minis for what they are. In addition to many other good words about the Mini, and some warnings, I tried to summarize and extend the good words in
post # 29 of that same thread.
Now, based upon your uses/interests as OP, and at the risk of going slightly OT, I ask you to consider whether the best thing about the Mini 14 might be the Mini 30? I think so. Unless you have thousands of rounds of 5.56x45mm stored up and desire commonality of ammo, the Mini 30 may serve you better (and the ammo is cheaper, to boot).
For hunting deer (which you mentioned) at < 150 yds (which is farther than most of us can humanely shoot with iron sights, which you also mentioned), the Mini 30 would be more humane. The .30 cal bullet has more stopping power, particularly the Prvi Partizan RNSP (round nose soft point). But just in general, the 5.56x45mm is a high-chamber-pressure screamer of a round but small diameter, while the mid-power 7.62x39mm rifle round the Mini 30 uses is no slouch and its larger diameter gives it much more energy transfer to most targets. It's worth a little thought and research. Here's a start, for the two most common loadings of the two chamberings:
