Which to add liquid vs powder tannin

[Cibb]

I've got 2 kits and 2 juice buckets and I feel a little tannin would help the wines. I'm intending to experiment with the amount but is liquid or powder preferred? Any particular place or brand?

I am partial to Scott Labs' tannins. I use FT Rouge as a fermentation tannin, and/or Tannin Complex for a finishing tannin.

Thanks. I'll order some. A few of my wines need a touch of tannin IMHO I just wasn't sure which to use or if there was a difference.
