I've had both. Don't have either one now. The one I regret selling is the Sheepdog. I don't care for tanto blades and none of the "7" series handles are as comfortable to me as the handles on the Sheepdog or Commander series. They may fit you better, I just didn't like them in my hands as much as the Sheepdog handles.
I had the spearpoint, PE. I liked the profile of the Sheepdog, but it was a little bigger than I carry as an everyday knife and I had enough folders already that were task-specific. I did like the spearpoint blade. It was very sturdy and well ground. The other turn-offs for me were the flipper and the bearings. I'm old, ornery, and set in my ways. I grew up with slip joints and strong backsprings or lockbacks. I don't want a smooth blade. I want one that doesn't move unless I move it and it stays where I put it until I move it.
But I still regret selling the Sheepdog. If nothing else, I should have kept it and given it to Jerry Lee to carry

. I think the Sheepdog is an outstanding "first offering" from Emerson in the world of bearings and flippers. Mine worked just like it was supposed to. It opened fully with the flipper and no wrist movement. It locked up every time... no misfires at all. There were no issues of any kind and it probably was the right size to be perfect for most "younger folks" these days.
