I wouldn't insist on a single best thing. Dropping someone over a cliff or holding them in a wall of fire is pretty darn good too.
Sure, but dropping them off a cliff can be done by Pushing them or Repelling Blasting instead of grappling them (Pushing is subject only to size limitations, not weight limitations), and holding them in a wall of fire doesn't require movement anyway, so carrying capacity is irrelevant. (Getting them into the wall of fire in the first place could be done by grappling, but only if you're willing to walk through the flames first yourself. Otherwise it's best done by Pushing.)
It would indeed be nice if the MM said how much creatures weigh, for that purpose. If your DM ignores the question and divides monsters into "small enough to move" vs "too large to move" and doesn't take PB into account, then obviously PB will be useless to you.
Speaking as a DM and a natural powergamer, I expect PB to be fairly useless to you regardless. There just aren't many creatures that fit into that narrow weight band where Powerful Build is relevant; and many of the creatures that do fit into that narrow band will be those kinds of somewhat-large creatures like Giant Toads that are so easily-slain that elaborate combinations such as "grapple + drag through wall of fire (taking damage in the process) + hold the enemy in the flames for several rounds" simply aren't worthwhile--you'd be better off just killing the thing. Yes, you could make an Orcish monk who grapples Giant Toads and drags them up 40' up trees with wall-running so the Giant Toads fall for 4d6 fall damage while the orc himself is fine--but it isn't hard to understand why most people don't want to!
Well, ktkenshinx rates goliaths gold and credits PB. I didn't see anyone in the thread disagree.
I stand corrected. I don't know whether kthenshinx is good at powergaming or not, but I'll take your word for it that he/she is a powergamer.
Doesn't change my actual point though, which was that it's not surprising when someone fails to get excited by Powerful Build.
