Hi Dave, Welcome!

I would lean toward the Uba Tuba myself. I'm not familiar with the Black Uba Tuba. We will also suggest TESTing your proposed granite. If you can get a piece of the slab that you are considering, do the following TEST.

Place a piece of lemon (or lemon juice) on the surface for about 10 minutes, then remove. Check and see if any dulling is present.

Place some olive oil on the surface for about 10 minutes. Wipe away. See if the surface has darkened.

If your results don't indicate etching or staining, you have a stone that won't even need sealing as well. If your results indicate no etching, but staining, your stone just needs to be sealed. If your stone indicates etching, not even a sealer will help (prevent etching).
