My favorite handgun format is still the revolver and it always will be. It does the best job of firing a cartridge. What I mean by that is we can use any bullet shape, any load the cartridge is supposed to handle, there are no feeding issues, the grips allow for extensive customization (almost any shape or material is possible), you can choose what kind of underlug you want, you can't limp wrist it, etc. From the perspective of doing what a handgun is supposed to do, I.E. sending bullets downrange, the revolver is a superior design in many important ways.
BUT...
For concealed carry, there's a lot of advantages to the self loader which in all honesty don't necessarily have a lot to do with the design of the gun.
The self loading pistol has a uniform flat profile which is much easier to carry for many and reloads, etc. are not as awkward to carry on one's person. Considering that job #2 is that it has to be carried constantly, that's a big consideration. For another thing, holster support for revolvers is lacking imho in comparison to a lot of bottom feeders, and holsters are as important to the concealed carry aspect as the gun is.
In addition, traditional service calibers are on the whole quite a bit cheaper to shoot in significant quantities than say .44 Special, .357 Magnum, or .45 Long Colt. Also, you have a lot more choices in premium JHP ammunition, which is the most bitter of ironies considering the diversity potential of almost any wheelgun puts any selfloader to shame.
Cylinder bulge and lack of aftermarket support have pushed me into the realm of the selfloader for primary CC consideration.
My take on it though, now that I've had a while to think about it, is that it only makes sense to have different guns for different purposes. After all that's why they make so many. CC isn't fun, it's not a competition, it's not a party, it's actually pretty mundane. It's okay to use a boring, ugly gun that doesn't particularly excite you. After all, do you get terribly excited about your socket wrench?
Plus, as I see it, it's a good time in history to be a revolver centric shooter even with the self loaders dominating the market, because the double action pistols we see that lack external safeties recreate two of the features I personally savor so much. While such a gun is certainly not a replacement for a revolver if a revolver is needed, it is a means of having the best of two worlds for CC purposes.
Finally, sometimes one format or the other will triumph for certain users in certain situations. For a true pocket gun, a true mouse gun, I much prefer the revolver hands down. Now for carrying tucked IWB, I want the semiauto. Going outside? Hand me the .44 Magnum...
Short answer: having a favorite is okay but use whatever is best for the job.
