there were the ups and downs of each system, but there were a few that stood out

I wasn't a big fan of having to buy your magic, like ff1 & 2, but the way it got stronger was helpful

FFIV's system was too standard

FFV's class/job system was great as not only did it offer to learn new skills but each class was unique and crucial to certain points in the game, that and it also let you build up your characters skills to create the best possible outcomes

FFVI's esper system was good too, it showed that you had control over the learning, and that anyone could learn any magic, plus there were characters with VERY useful skills of their own (I wouldn't be anywhere without Edgar, Sabin, Gau and Celes)

FFVII's materia system rocked, but the only problem was it took too long to level up the materia.

The junctioning system in FFVIII was good in the sense that you didn't have to level up your characters millions of times to make them potentially strong characters. If you knew how to use the refinement skills and the drawing technique, you could build yourself really strong characters in a very short time, problem was that you then had to rely far too much on that magic, and couldnt use it in any fights. And until you understood how to junction, it was very had to get used to.

FFIX's system of learning off the weapons wasn't too bad, but it was very standard style stuff. There wasn't much in the way of bettering your characters faster.

most people i talk to don't like the sphere grid system, but i thought it wasn't all that bad. The only thing i didn't like about it was the fact that it took a very long time to see improvements to your characters, and although each character starts with their own specialty, eventually they all end up the same anyway.

FFX-2's dressphere system was good, being able to change your class in the middle of a fight was actually really helpful, but it could've been a little less girly -_- when it came to the way of learning new skills it was pretty easy and moderately fast so it was a good thing.
