One thing I really like about Unique is that it is extremely versatile. There is not one handgun caliber or bullet weight it does not work well with, or shotgun gauge for that mater. I always keep some Unique in my stock just in case I run out of something else. It does burn cleaner than it used too but it is still dirtier than Power pistol. PP gives much more mussel flash and performs better at or near max loads than Unique. PP was designed for the calibers you listed and would be my preferred choice in them. However I wouldn’t be opposed to using Unique in a pinch.
