Baseball grip? Not sure if serious.
There have been pros that have used a 10 finger grip, although I can't think of any famous pros that used it off the top of my head. I'm sure there have been a few though. It seems to me that a baseball grip would encourage proper release of the club, but possible at the expense of one had dominating the other. To me this could be the most powerful grip, however and the expense of as much of a loss in accuracy. That's just my opinion. to me, it seems it would be easier to manipulate the club (a bad thing in golf) with a baseball grip as your hands will cover a slightly larger area on the shaft.
The interlocking grip is probably best for someone that has smaller hands (ie women). It does a great job of fusing the hands together. Nicklaus and Woods have used an interlocking grip. I'm not sure about Woods, but look at any picture of Jack Nicklaus not holding a golf club and just look at his hands. They're tiny. They're porportionally smaller than an average person. The only drawback as that it can lead to you holding the club too much in the palms. I've tried it on the driving range a few times and didn't care for how it felt.
The overlapping or Vardon grip is by far the most popular among pros. It encourages you to hold the club in the fingers and joins the hands as one unit working together better than a baseball grip, but probably not as well as an interlocking. Harry Vardon, the golfer that gave the grip it's namesake (I don't think he was the first to use it though) had huge hands with very long fingers resembling cigars. My understanding was that that was the primary reason he used it.
