I currently have an SU-16A, am seriously considering buying a Mini-14, and have fired both the SU-16 and the Mini-14. Both are nice weapons. The SU-16 has many things going for it. Plentiful and reliable magazines, its marginally cheaper than the newer Mini-14s, arguable more accurate out of the box, lighter, and can easily mount optics on it. The biggest complaint that I have on my SU-16 is how much recoil it has. For a .223/5.56 carbine, it kicks a lot, which makes sense for such a light rifle. Others complain how the SU-16 feels cheap. The Mini-14 has some things going for it, it feels better made, less felt recoil, more aftermarket add-ons, and can be easily made to be as accurate if not more accurate than the SU-16. The major problems with the Mini-14 are finding reliable magazines, accuracy problems associated with the thin barrel, and durability problems associated with hard use of the rifle. I personally think both the SU-16 and the Mini-14 will both suffer from durability issues from hard use. I have never heard of any SU-16s breaking down from hard use, but there are fewer out there, and have most have not had as many rounds put through them as many of the Mini-14s. All of that being said, both are fine rifles, and a lot of it comes down to personal preference on which one you will eventually buy, I would try to fire both, and it that is not an option I would at least handle both to see which one fits you better.
