Considering you opted for the 3.75" Gerber Decree, (which you found too big for your edc wants and needs)
I would strongly urge against a Spyderco Delica at less the 3" in the blade (2.5" cutting edge), because most likely you will find it too small... The name Delica says it all, as it is a more delicate cutting tool, reminds of an exacto knife on steroids! No, seriously...
If you want to drink the Spyderco koolaid, and I have no issues if you do, they are very quality built knives, opt for the Endura, as a tweener between the Delica and and Decree (size wise)... It is virtually a large delica; you don't want to be goldilocks here and go too hot, too cold, and then have to seek a just right option...
The Centofante III is a wee bit bigger then the Delica also, with a much better overall design (thank you Frank), and all the same sliciness as a Delica, more blade, more handle, same Steel, same weight... Only real draw back is you can't buy it in pink, (or blue, purple, etc).
It's the only Spyderco I keep thinking about buying....
