If the strength of the blade on the delica ffg worries you keep in mind it is available with a saber grind. I prefer the minigrip for edc but only because mine is a Ritter with custom scales and it is more fun to play with. The delica is probably the more useful, utilitarian blade.
the benchmade is probably going to give you the most satisfaction when you open the box, but in actual use, the delica might be the better knife...
