I prefer 3blx over 1blx the majority of the time.

The NCAA mechanic is point-of-plate as the standard default, and then adjusting to the play to use whatever positioning allows you to see what is necessary.

As others have noted, there are times when 3blx is clearly NOT the place to be, when the catcher is set up to block the plate and the runner slides straight in; you cannot see if the runner reached the plate, and even have a poor position to judge obstruction (if contact occured before about-to-receive). On the other hand, 1blx is a bad place to be when the throw pulls the catcher deep and the runner then slides to the front side; and is weaker than 3blx when the runner slides to back door.

Each play is different; point-of-plate allows the most adjustments as the play develops.
