Depends. Which interests you more? Time travel, animals, or space?

I've really been enjoying Den-O, it's pretty fun, a bit goofy, but it also has some pretty serious elements to it. OOO was also fun, kinda goofy to start out, but getting more serious as it went on, and the story definitely got betters. Fourze, I'm not caught up on, but it's also fun. I'd say they're pretty comparable, in my opinion.

I find Eiji (OOO) and Gentaro (Fourze) to be better main characters than Ryuotaro (Den-O), although every once in a while he really impresses me. Den-O has the better supporting cast, in my opinion, I really like them Imagin, Hana, Naomi, Owner, and Yuuto. I also really liked Ankh in OOO, but didn't particularly feel one way or the other for any other supporting characters, except maybe Satonaka and Kougami. The supporting cast on Fourze I'm neither hate nor love yet, but I like them okay.

As for the villains, I thought the Greeed were fine, great designs, but off and on again as far as their threat level, at least until Maki. The Horoscopes are really interesting me, so far. And I'm only just getting to where there is a main villain on Den-O, and there's only 9 episodes left. The Imagin of the week are usually visually interesting, but the focus up to now has been more on each individual story arc, rather than an overarching goal.
