I don't own either a Demco or Cold Steel. that said, I'd take a Demco AD20.5 over Cold Steel any day. It's personal preference/opinion, but there just aren't any Cold Steel models that I want. The Demco AD20.5 is another matter. And they offer them in a good variety of steels too. Of the newer steels, the S35VN is probably my favorite. It offers just the right combination of edge holding vs toughness vs ease of sharpening. I have knives in the 20CV, and while they hold an edge longer than S35, they're harder to sharpen. 

As far as carrying a $400+ knife every day, I have absolutely no problem with that. I have 4 Chris Reeves & 3 Hinderers, and I have no problems, carrying, using & getting them dirty. I've been sort of on a Buck knife kick lately, but one my Chris Reeves knives was usually clipped to my pocket for a long time before that , and will most likely end up there again soon.

I almost always carry a large & a small knife, and I go on binges, and have new favorites from time to time, but a Chris Reeve & an Alox SAK eventually always end up back in my pocket.

I just ordered an AD20.5 Black G10!  I really wanted to get an MGAD20 but it wasn't in the budget this round!  My 20.5 will be S35VN but I guess I am more of a collector than a user!  I do carry my knives though but usually in my lunch bag, LOL.  The SAK is the main knife in my pocket!  If you like the AD20.5, you should check out the Cold Steel AD15!  What a freakin' beast!  Absolutely love mine!  I only wish I could get my hands on a Demko version at a good price!
