While stp vs pte was already thoughtfully discussed in this thread (and neither of the cards turned out to be strictly better than the other) I wonder about your thoughts on one more issue, that hasn't been widely covered - targeting your own critters.

In a pitch you can use stp as a lifegain tool, while pte can be used as land tutor tool. In order to be efficient stp must be used on a big guy (which often will mean goyf only), while pte can work even on 1/1 kird ape. Both can be used in response to spot removal and when we are chump blocking (too bad damage no longer goes on stack). It also makes both cards not totally dead against creatureless decks.

Is any of those plays occasionally important or are those just tricks which will never turn the tide of battle for you?
