Both are terriers, and hence, well, they're terriers--stubborn, smart, and active. Personally, I love wheatons. We had one who had been raised by someone who was up to raising a terrier (that wouldn't be me), and we got him when he was 8 (his original owners couldn't keep him anymore). He was a wonderful dog, very sweet, loving, determined as all get out, an incredibly mentally tough dog. My observation is wheatons are very determinted and energetic, but not as hyper as the mini or standard schnauzers (though I've never owned a schnauzer, just observed them in dog parks).

Wheatons do have some health issues, however, especially congenital renal disease, so if you go with a wheaton, check into the breeding carefully.
