Personally I love Moras. I have other knives but I have yet to find something I like more than a Mora. I carry a Mora and a small axe in the bush and I've never, ever, ever found myslef poorly equipped.
Honestly I don't know what I would want a big knife like a 7" Becker etc. for. Some people seem to do chopping tasks with them but I use my axe for that and I'm certain the axe is better for chopping!
I can't claim to have personally tried this but I read last year that the Canadian survival expert Mors Kochanski favours Moras over pretty much anything, and his description of the torture tests he uses to determine a good knife are not for the faint of heart! Pound them two inches into a tree, stand on the handle, etc, etc.
Anyway I love my Moras and while I'll switch if I find something I prefer, so far I haven't even come close to switching brands! And for what, ten bucks? How can you go wrong?
