Yeah the controls are the big sticking point with enjoying Armored Core. The only one I got through was the first one. I bought it because it has one of the best game soundtracks I've ever heard. However when I played it, most of the levels had silence for BGM. I thought it was supposed to be like that, but later found out it was a glitch (I looked it up because when I was most of the way through the game I'd only heard like 5 tracks the whole time). I think I was playing it on PS3, and sometimes PS1 games would be iffy on PS3. Armored Core missing most of the soundtrack, Alien Trilogy being so dark it was unplayable (that one hurts), etc.
