I was in the same boat as you a few years ago, never really liked the Spyder hole. Too weird looking, made the knife bulky, didn't think it could open quickly.Now, I think it's awesome. Incredibly intuitive way to open the knife. Opens wet, muddy, with gloves, with numb hands, anything. Big enough that you rarely have to dig around for grip (even on models where the hole can be somewhat occluded, like the Native).
Well now that we're confessing on Spyderco issues...
