I was going to point out what Old Fluff already said - finger grooves are the bomb -
if they fit you. I have discarded (sold/traded) more fancy finger grooves that I have bought than any type. I put two or three different pair of finger grooves on my other 1/2's (or as M. Ayoob calls them "my adult supervisor") 66 snubbie, and she hated them all - now she's using the original factory magnas and liking them better. Only one of my guns has finger groove grips now. That one also doesn't fit perfectly correct, but they were original to the gun and look great, so I tolerate it. Also, on magnums, having your fingers touch provides mutual support for them for control.
An old-time S&W guru told me a few years ago to try smooth grips on magnums. They actually provide MORE contact than checkered models (surface to area) and are less unpleasant to shoot because of the lack of bite. They require a slightly firmer grip for equal control, but that is not a problem once you understand it and use it that way.
The "under clothes" argument/reason is very valid to me. None of my guns have rubber grips, and few of them have checkered grips, partially for that reason (and also the reason above).
Here is what I ended up with on my 686 after trying quite a few grips from rubber, to magna style, checkered targets, etc. I think you'll see why I voted "bottom left." I love these grips. The fullness of the factory grip but
without the constraining checkering is a perfect match for magnum calibers and getting maximum hand contact for control. I understand why, say, Miculek uses the shape he does. I have average "male" hands - I wear a L glove size consistently - not overly large or small. These fit great, whereas the same factory grip with checkering feels too large and uncomfortable to me. If you hands are M to L, then go with the Ahrends (they will be cheaper than finding these vintage grips), but if you are XL or larger, maybe the factory ones will work better for you.
