Springfield Armory XD Mod. 2 sub-compact. Reliable and accurate; shoots everything and shoots well. Next is CZ P-07, also a reliable and accurate gun.
I have 4 40 S&W guns.
A FNX 40, a FNS 40, a Shield 40 and a Gluck 27.
The FNS 40 is my favorite. Very accurate and very easy to shoot. The FNX 40 is also exceptional, however I normally have a 357 Sig or a 9mm barrel in it. The Shield is also very good and I often carry it as a pocket pistol.
