I'm not much of a striker fired person, but...
I like the Caracal, especially the quick sights. I think they're probably the best design when teaching a new shooter how to acquire a proper sight picture. That being said...
It's still impossible to beat the Glock in terms of holster options, aftermarket accessories, cost effectiveness... despite not liking the grip angle, I'd say the Glock is still the best striker fired pistol on the market. BUT... not my favorite.
My favorite is the Walther PPQ. No real logical reason. I like the way it looks, like the way it feels... I probably won't be getting one though, at least not for a good while since it's so low on my priority list. But, it is my (current) favorite.
