What do you intend on using it for? If "EDC", what do you find yourself doing and/or cutting in the course of a day? Do you work in a school or an office, or otherwise around people who may not appreciate 4" blades flashing around?
I prefer larger knives and big blades, but find they attract too much unwanted attention in such an environment. So I've taken to smaller knives, and find the little blades do everything I need them to. Again, I'm not quartering game with these knives, just doing day-to-day chores.
A stockman will have smaller blades that can be used at times like these. If that's a consideration, you might consider it. If not, heck, get the biggest baddest banana trapper out there and scoop the peanut butter till the cows come home.(I love trappers, too.)

I never really cared for the trapper pattern until I had to cut up some fruit - apples, oranges, etc. Then I tried it on bagels. I have lots of people that ask for me to cut their bagels or borrow it, no one has yet been put off by the size - they don't talk much with their mouths full!

I don't know why, but I still prefer the stockman overall, probably because of the blade size mix like others have said. I like the sheepsfoot for delicate work, and usually grind it down very thin. This is exactly the opposite of what it was designed for, and what most people do, but there you go - something for everyone.
Get both. You'll appreciate them both for different reasons - they're both great!
