I think 8chan is superior in technology, setup and privacy (it has an onion site; works just fine without JS; does not rely on Google for CAPTCHAs) to 4chan. But the userbase just isn't the same. Without any real culture on some of the boards, it never really feels like 'home' like /int/ on 4chan did for me.
So, yeah, it's really a balance between technological superiority and (at least on some boards with 4chan counterparts) cultural inferiority.
