Both series use still shots and slow motion. <_< Old one had plenty of those, even with that weird texture thing on it.

But you won't find stuff like this or this in the old one.

Natsu vs. Cyclops bird. Gray and Juvia vs. Atlas Flame. Natsu using Atlas' flames vs. Motherglare. Erza vs. Minerva vs. Kagura, to an extent. Those all had fluid, well looking animation that can hardly be found in the old series. In comparison, the start of Team Natsu vs. Hades had great fight animation, but I can't really think of anything else from the old series that I would consider outstanding in that way. And I've rewatched the series with a friend just recently, up to Edolas arc.
