I have used the 10 finger (base ball) grip in the past. I actually started out with it. I was a baseball player before I took up golf, and the 10 finger grip felt comfortable. Shot decent scores with it. I played with it for several years before switching to the Vardon grip, which I have used for the past 30+ years or so. When I switched, it was because I felt like the Vardon grip gave me a better release into, and through impact. About 10 years ago I gave Furyk's grip a go, and liked it, but for some reason gravitated back to the Vardon grip. I suspect it was a lack of confidence in holding onto the club, and club face control. I even tried Moe Norman's grip which I thought had some merit. I still mess around with his palm grip from time to time for some of my shorter shots. I never tried the interlocking grip for any length of time due to it feeling really uncomfortable, and I do mean uncomfortable. I suspect my fingers were not geared for that grip.
I guess my point is that any grip is fine, as long as it gets the job done. I also think that those folks just starting out with their golf game, should try the different grips just to get an idea of what might work best for them. Problem is, that most golfers won't give a new grip enough time to make a qualified decision. I used the interlocking grip for about 6 months before casting it a side.
One of the other things I like about the Vardon grip is that I also use it when putting. I don't have to switch grips in different situations.
