1st Choice and everyday carry is a 1911A1 in 45ACP. Kimber IMHO is the only company making one that does not have to be tweeked out of the box by a gunsmith. Peek at the Kimber Stainless Pro Carry for that one. My 1911A1 is a custom Clark Meltdown.
2nd Choice of late is the new SIGP239 in 40 Short & Wimpy or .357SIG (I have both barrels and mags so I swap calibers sometimes).
I have a Glock 23/19/30/21/34/35 and like em all. The SIG 220 in 45 ACP is a great duty gun as is the SIG 228 in 9MM. The browning High powers are really nice too. My addiction starting to show yet ?
Key is to get what works for your needs. If a CHL day to day carry then weight and carry concerns are primary in some cases.........Lots of possibilities .
My choice is the 1911A1 as that is what I have carried and used the most and I tend to lean towards something I call muscle memory-matic when it comes to speed , presentation and accuracy in self defense mode.
Hope I helped, ....Stay Safe !
