My life would suck without you
I'm not really a fan of using either of the two. However, my vote will go to Emboar because I found it much more useful in-game. Going solely on competitive, I'd pick Sawk because of how useful Sturdy is, but when I used Sawk in my Hall of Fame Challenge, it didn't fare as well as the other Pokemon on the team. Emboar on the other hand wasn't bad, and its largeish movepool was good.
