I don't like putting from off the green. Maybe it's from playing at courses where the fringe is pretty rough (bumpy). In any case I'm no good at it and have always been a decent chipper (until last year anyway). If the grass has been trimmed nicely and the grain is headed the same way as the putt I may putt it if it's not more than three feet off the green and the fringe isn't bumpy. If the pin is more than 20 - 25 feet away, I'll still chip it.
