Given the ones you have listed I would chose titegroup or Red Dot/Promo. My pro disk will throw 4gr of promo + or - .1. (bigger flakes than Unique but meters better for me)
Titegroup has a vmd of about .085 so the .34 disk will throw about 4gr. My can of Promo has a caculated vmd of about .14 so to get 4gr I use the .56 disk. I like titegroup but it does not fill the case well and you could easily double charge a case if you not careful. (triple charge will fit) Promo fills a 9mm case nicely, a double charge would over flow.
I would tie those 2 for first, chose Power Pistol next, then Bullseye.
My caculated for the lb of Bullseye I currently have is .105, for Powerpistol
.091 so they are somewhere in between Titegoup and Promo.
I use 4gr Promo in 9mm with 124/125s and the same 4gr in .45 APC with 230s.
For 9mm I have had good results with 3.9 of titegroup but 3.7 was softer and really close. (prefer 3.7 lead coated, tie 3.7/3.9 with plated)
If you are after stout (close to MAX or MAX) I would say Power Pistol for sure. (big muzzle flash)
PP does take more powder per round if you are pinching pennies.
Hope you have good luck with whatever you choose, I have used all of them and all work in 9mm. (still prefer Universal as my first choice)
As a side note I have had good luck with WSF, and sometimes you can find it because it does not seem to be well known/popular. (meters well)
