<< Just for the style? >>
Sure, there are people who buy revolvers for the style.
<< Isn't a semi auto pistol preferable to a revolver? >>
To some people, yes. To others, no.
<< Holds more than six, easy to reload(clip fed) etc. >>
There are revolvers that hold up to 8 rounds. That's not a whole lot less than the current federally mandated 10 round limit for semi-auto magazines.
<< I admit revolvers are cool, and they tamed the west, but they seem outdated. >>
Revolvers are generally thought to be more reliable, the mechanism is more simple.
Revolvers and pistols are traditionally offered in different calibers. Revolver rounds are generally the more powerful and the revolver frame is better suited for more powerful calibers.
You can get revolvers in any pistol caliber, but you can't get pistols in every handgun caliber, or at least they are far less available. In order to offer a pistol in traditional handgun magnum calibers, you need an unconventional action (Desert Eagle) because the recoil from a common revolver caliber such as .357Mag will destroy a conventional pistol in short order. Feeding and extraction is also more problematic with longer rounds, requiring an unconventional action.
Revolvers are generally more accurate to a greater distance than pistols because they are available with longer barrels, the barrels are rigidly fixed to the frame, and the bullets leave the barrel with more velocity.
Technique is more critical for firing a pistol. If you limp wrist a semi-automatic, you run the risk of feeding and extraction problems. No such problem is inherent in a revolver.
All semi-auto pistols except double-action only demand greater diligence and training because, although revolvers typically don't have a safety, a semi-auto that is "cocked" only requires a few milimeters of trigger pull to discharge and it automatically loads and cocks itself for the next shot, whereas revolvers have a long and heavy (comparatively) trigger pull each round unless you manually cock the hammer.
