There is no such creature as the "best" concealed carry weapon...well, other than a lightweight commander in .45acp
Back to being serious - there is no such thing as an across-the-board "best" concealed handgun (even though many gun manufacturers, fan boys and gun mag writers will try to tell you otherwise). There are far too many factors such as regional weather conditions (you can easily conceal a rocket launcher in winter), body type, occupational dress requirements, all sorts of individual-specific hand-fit issues (hence, the "try before you buy" rule), etc. -- all of which come into play. As such, it is impossible to say there is a "best" gun for everyone.
For example, I 6'4" and right around 250lbs - I can conceal pistols the size of a Glock 21 in spring, fall and winter without any problem - in part because my occupation normally has me in a suit and tie. Additionally, the thickness of the Glock 21 doesn't bother me because I have relatively large hands. In contrast, a Glock 21 sized pistol is not going to work for a guy that is 5'7" 165lbs that goes to work in a polo and khakis...well, unless he works in a gun store.
While I can carry really large pistols, I usually do not carry anything the size/thickness of a Glock 21. A single stack .45 is a much more realistic option for me when it comes to day-to-day carry. In fact, I find it considerably easier to carry a single stack .45, 1-2 spare mags, a single stack 9mm backup and a really small .380 (backup-backup) than most double-stack pistols along with one spare double stack mag. I am sure plenty of people believe the opposite is true and it likely is for their particular situation.
The fact that there is no best gun for all conditions is actually a good thing -- it's a perfect excuse to keep buying more guns.
