It's up to you which grip to use, but most players don't grip the putter the same way they do their other clubs.
What matters is that your hands are comfortable on the putter, and that you are not "twitching" trying to find a place to put your hands. FWIW I use the same grip on my putter as on every other club in my bag. I don't need a reminder where to put my hands and when you are faced with those incredibly weird little shots you sometimes have to hit with the Texas Wedge, having a regular grip makes it easier to "feel" how to maneuver the club or to re-grip it.
