It's not a contest. I love Korpiklaani. I love Ensiferum. Who gives a shit which one is "better"? Does that suddenly make the other not worth listening to? No band "has shit on" your favorite band, and yet you probably listen to more than one band. Their styles aren't even comparable; the only similarity is the folk element.
The video is hilarious. This is how a folk/viking metal video is done.
