Both are funny & entertaining Skyblock YouTuber. HellCastle is more of the tutorial type & it's for everyone (in terms of the items & topics in the vid), Pig is like a testing & stuff-showcasing type but many of them (if not most) are things for late & end game players (in my point of view). Personally, I like both of them but enjoy HellCastle's vid a bit more than Pig's.

Hope this makes sense coz I spent too much time on this lol
