There are advantages and disadvantages to both.
A revolver's strong points are as follows:
-A double-action revolver has one of the simplest manual-of-arms available. There are no manual safeties or magazine releases and the loaded/unloaded status can be verified by simply opening the cylinder and looking.
-A revolver is more reliable under certain conditions such as a contact-distance shot, a shot from underneath a cover garment, or a shot with an improper grip due to a weak or injured hand.
-Revolvers are more tolerant of a wider variety of ammunition including FMJ, LRN, SWC, HBWC, JHP, LSWCHP, and even shotshell loadings. Also, a revolver will not fail to cycle due to lighter than standard loadings. So long as there is enough pressure to get the bullet out of the barrel, a revolver can continue to function.
-A revolver can offer a better power-to-size ratio than a semi-automatic can. Few semi-autos can offer the power of a .357 Magnum in a gun the size of a small-frame, lightweight, five-shot revolver. Likewise, few semi-autos can offer the power of a .44 Magnum in a package the size and weight of a DA revolver in that caliber.
-Revolvers do not require magazines. All that is needed to use a revolver is the gun and a handful of cartridges. Also, a revolver is much faster to reload if forced to do so with loose cartridges.
-Revolvers typically have more rounded contours which make them easier for some people to conceal. My S&W J-Frame just looks like a generic lump in my pocket while my Walther PP (the closest size semi-auto I own) has more sharp angles that scream "gun".
-Because the gripframe of a revolver does not have to contain a magazine, there is a wider variety of aftermarket grips to tailor a revolver to the individual shooter's hands. I've found that putting Houge grips on my revolver can make a huge difference in the handling of the gun while I'm pretty much stuck with the grip shape on a semi-auto.
A semi-automatic has its own strong points too, they are as follows:
-A semi-automatic can be had in a much higher capacity package than a revolver. Revolver typically have a capacity of anywhere from 5-10 rounds depending on the caliber and gun while a semi-automatic, particularly one with double-stack magazines, can easily have a capacity of 10-20 rounds.
-Semi-autos can be loaded much faster than a revolver so long as pre-loaded spare magazines are available.
-Semi-autos are usually a more "closed" design and are thus better at keeping mud, sand, and other debris out of the action.
-Semi-automatics are usually slimmer and flatter which are attributes that make them more concealable for many people.
-Semi-automatics offer a better power-to-recoil ratio than a revolver. The reason for this is that the cycling of a semi-auto's action soaks up some of the recoil.
-Many semi-autos automatically re-cock themselves for a lighter SA follow-up shot. Some people find semi-autos easier to shoot because of this.
-Because of the lack of a cylinder, a semi-auto can be made with a lower bore axis than a revolver.
As I said in your other thread, I wouldn't really worry all that much about bore-axis as there are many other factors which influence your shooting to a much greater degree. For example, there are three basic styles of DA revolver which are commonly available: Colt (Armscor revolvers are based on the Colt Design), Ruger, and S&W (Taurus, Rossi, and Astra revolvers are all based on the S&W design). Given similar sized revolvers of all three designs (for example, a Colt Official Police, Ruger Security Six, and S&W Model 19), a Ruger typically sits the lowest in the hand followed by S&W with a Colt sitting the highest. Even so, not everyone is fit best by the lowest-sitting gun. I personally find a S&W to fit my hand the best while my dad is fit by a Ruger.
As far as follow-up shots go, barrel length, weight, and ammunition choice will play a much larger role than bore axis. Given guns of similar weight with identical ammunition, a gun with the longer barrel will typically allow faster follow-up shots than a gun with a shorter barrel. Likewise, given guns with equal barrel lengths and identical ammunition, a heavier gun will dampen recoil and allow faster follow-up shots than a lighter one. Finally, the more recoil the ammunition produces, the slower the follow up shots will be. Also, if you have two loadings with similar recoil in the same gun (a 125grn .357 Magnum and a 158grn .357 Magnum for example) the loading with the heavier bullet will typically produce more muzzle rise and thus slow follow-up shots.
I wouldn't worry too much about slow recovery times with a .357 Magnum. One of the nice things about this cartridge is that it is versatile and allows you to tailor your ammunition choices.
-Standard pressure .38 Special loadings have rather light recoil which most people can handle with little trouble.
-.38 Special +P ammo usually gives somewhat better performance than standard pressure ammo but still has moderate recoil in a medium or large frame revolver and usually isn't a problem unless the shooter is recoil sensitive.
-"Mid-range" or "medium velocity" .357 Magnum ammo like Remington 125grn Golden Saber, Speer 135grn Short Barrel Gold Dots, and the 110grn JHP loadings from Federal, Remington, and Winchester will give superior performance to most .38 +P loadings and are still quite manageable for most people from an all-steel medium or large frame revolver.
-Full power .357 Magnum ammo such as Winchester Silvertips, Federal Hydra-Shoks, or the 125 and 158grn SJHP loadings from Federal, Remington, and Winchester gives the best ballistic performance, but also has fairly heavy recoil. This ammunition is best for reasonably experienced shooters, particularly if a small, lightweight gun is used.
