I'm going with Robbaz on this one. Viking commentary on his videos that makes it much more interesting.

I haven't watched Robbaz so im going to go with Jesse Cox ( Omfgcata )

Robbaz is really funny if you are ok with some vulgarity and swearing, he's swedish and has an amuzing voice and talks about how no one messes with a viking. Some of his videos have over a million views so someone has to like him. I'll check out this Jesse Cox though.

I actually watched Robbaz once. I have nothing against vulgarity and swearing as long as there's something funny behind it. With Robbaz, there isn't, it's just the vulgarity and a (possibly fake) accent.

Orcideas videos are always extremely helpful

I like MrRhexx, he makes awesome machinima, but an upcoming guy that I really like is fl333r. He's not me, go check him out.
