Fine to use pool chems if in balance?

I’ve noticed stores stock “spa” and “pool” chemicals, each seeming to be approximately the same but the spa versions being almost double the price. Am I fine to use pool chems as long as things stay balanced when testing water? Or is there something special about the spa versions - maybe designed for warmer water temp or something?

EDIT - some complete opposite answers haha.

I’m using bromine.
