What breeds for a newbie?

I'm looking to acquire a couple of goats to graze my overgrown 1.5 acre pasture. Previous owners kept a mule and cow and it has fencing around the pasture and a small 2 stall shelter. I don't plan on breeding, milking, shearing, or otherwise using these goats for production. They're just to graze the pasture down a bit and hang out.

My question is, what breed would you suggest for a new goat owner? There are mostly Boers, Nigerian Dwarfs, Pygmys, and various mixes of the three around me.

I have heard some talk of how larger goats are easier keepers than the smaller breeds, has that been your experience?
