What other brands have you owned?
My first "big" folders were a Smith and Wesson Swat, Gerber Chameleon2, Gerber Gator, and Gerber EZ Out.
After buying Kershaws, BMs, and Spydercos, (and not to mention gerbers rapid decline in quality in the past 10 years) I've realized that there are much much beter knives out there for about the same price. Every gerber I have handled in the past 5 or 6 years has been cheaply put together, not very sharp out of the box, and good luck finding info on blade steel/heat treat. When I sold knives, Gerbers sold to people who just wanted a knife and didn't know anything about steel. People who knew or wanted to know what steel was in the knife they were buying so that they could make sure it would stand up to their specific needs went with other brands. Why? Only on US made gerbers (very few US made models) would say on the blade, box, or gerber's website what the blade steel was made of. Everything else just said "surgical stainless" or "400 series stainless". "400 series" means 420, 420HC, 440, 440A, 440B, or 440C. There are considerable differences between all of those, and I would want to know what exactly is in it so I could be sure if it would hold up to my standards. That's my main beef with gerber.
Back in the day, Gerbers were awesome. I would still take any of their U.S. models (Gators, LSTs, LMFs). But since most of their knives are being cheaply made overseas (not a bash.. some overseas knives these days are not cheaply made. ex. Spyderco's Byrd line or Tenacious). They just aren't all that great anymore.
Thats what you've missed. From my side of the fence. However, If you are satisfied and think you get your money's worth and they perform how you need them to perform, by all means keep buying them!
