Serial is the go to but with episodic bits too keep the show refreshed. Like how Gaim would occassionally have single filler episodes in between as a breather, like the Gridon and Bravo episode, Kikaider and summer movie tie-in. Granted, the latter two interfered with the storyline a bit, but at least they kept the show breathing.

I don't mind episodic if it is done well especially in W and OOO, but it can be prone to filler, as Wizard demonstrated. Hell, people argued that Drive's first half wasn't as strong, it's mostly due to the episodic nature (though I'd argue people thinking it was weak because Gaim before was a heavily serialized show)
