I don't have any such favourite arcs in any anime as of now.
What about you guys? Please note that, this is not related to any one anime

Naruto - the first 8 tails arc.

Bleach - the last filler arc (forget the name of it)

DBZ - namek arc

Eh, thats all I can recall right now.

Choose just one in those four arcs.
If can be only one arc at the end. It's for all the anime in question

I'd say the 8 tails arc then.
