I've got a Mini-30 and a cheapie AK and will tell you what I can about each.
I bought the Mini-30 back in the Clinton -Reno era so its a relativley older rifle and likely bored .308. I have shot a bunch of steel case ammo through it, Norinco (chinese) and Russian Wolf and others, and it has run fine, AS LONG AS I USE THE 5-RD FACTORY MAG. The early hi cap mags for the mini-30, non Ruger, are all mostly junk. I bought several right before the magazine ban and they were just not worth it. Now that Ruger is making a RUGER 20 rd mag for the Mini-30, that is a big plus for the rifle.
I have NOT broken any parts, worn out the factory mag, or had any failures to fire, and again, as long as I use the factory mag, the rifle runs nearly flawlessly. I have also loaded for my Mini-30, and shot a wide variety of domestic soft points (123-125 through it w/ no trouble. I worked up some loads using GI 147 gr FMJ slugs, 150 gr FPSP, even 150 gr Sierra Match Kings. Bamaboy and I use the 7.62 x39 ctg for our whitetails w/ no problem, we are taking our deer inside 100 yds and at those ranges the x39 ctg (w/ quality slugs) does fine. The Mini currently wears a Leupold 1-4x equipped with a chunky German #1 reticle. One of the pluses for the Mini is that it is easily scoped and ususally comes with factory rings, or they are easily available. They have useable triggers that do not slap, and a practical safety. If not scoped, the factory peep, either the old folder, or the newer winged version, is worlds better than the short radiused AK sight which gives anything but good eyes fits. I have not kept a log on the rifle, but the round count is in 2 thousands and I have seen none of the problems you see mentioned regards the Mini-30 often mentioned by others. The rifle shoots into 2-4 MOA depending on what ammo its fed. A simple field strip of a Mini yields 3 big parts that are not easily lost. Its one piece wood and steel appearance is somewhat conventional, points like other sporting rifles and I would choose it as a hunter over my AK.
The AK is likely the cheapest AK that is out there, an MISR-90, that I tweaked up to 922r compliance. Any AK mag seems to run fine in it, I like the 20's. It is as reliable as you would expect an AK to be and I cannot recall a failure/jam. With import ammo it shoots 6-9 MOA and that is likely generous estimate. It cannot be easily scoped, and the trigger would beat you to death with slap till I put a Tapco in it. The short sight radius gives me FITS. I have hunted w/ it (5 rd mag) just to say I have, but never taken (or shot at) a deer with it. The Delta Point set up posted earlier looks great, but the mount and sight will cost twice what I have in the AK!
If I had to defend my home and property, (looks and liability aside, althoght the 870 and a coach gun stay loaded in reality) or was in a war zone somewhere, I'd grab the AK and not the Mini.
