I think the emphasis should be on putting your finger on the trigger where it gives you the best chance of squeezing straight back towards the grip and not pushing or pulling left or right. For most people on most guns, that will be somewhere on the pad between the fingertip and first joint.
But, for a particular individual with a particular gun, the best mechanics to create a trigger pull that moves straight back could be a little more towards the tip or a little more towards to first joint. The idea is to give yourself the greatest chance of moving the trigger straight back with no lateral pressure.
With my subcompact I feel I put the best rearward motion on the trigger by favoring the first joint rather than the tip of my finger.
Here is a photo of Brian Enos' grip. He has so much finger on the trigger that the tip is outside of the trigger guard.
Here is Dave Sevigny's grip. You can imagine a line down the middle of the slide to represent the trigger. Clearly, the trigger is nowhere near the tip of his finger. Again, you can see the tip sticking well out the other side of the trigger guard.
