Art = the way the characters are drawn, their looks

Animation = the way the characters move, the fights, etc.

And with that said, I think the new anime handles both of these better than the old anime. Of course, there are times when the new anime derps hard, but the same goes for the old anime. However, in general, I think that the new anime has upped the quality quite well.

Look at this fight. Now try to find animation as good as this one in the old anime. You won't be able to.

Then we have Gray and Juvia battling Atlas Flame. Or Natsu owning Motherglare. Can't find such animation in the old anime, for sure.
