I have the sheepsfoot with the spydie hole and love it. I believe the sheepsfoot blade has a thinner grind, which makes it a superior slicer (but maybe also more fragile for any abusive work). I'm not a fan of thumbstuds so I wouldn't get one like that, not even the Ritter. Contradicts my 'high speed, low drag' proclivities, LOL.
My only wish is that mine had the G10 handles, so if you can opt for that, I'd say do it.
