Instead of brick, which is porous and not a great choice for backsplash tile, consider the glazed thin brick from Fireclay Tile. It will give you the look your going for, but be much more hygeinic, and easy to maintain.

Lots of good options.

So two totally opposite looks. For all the reasons stated above, stone I find counter indicated. I would caution the use of glass as I think it's out lived it's time. I am loving the newer solid piece material look, and I would go with one with a subtle veining over busy as I think one tires more quickly of an overly patterned back splash.

IMO neither of those i think brick is too pourous and I do not like mixing real stone with fake . I happen to love glass tile and often it is just the right amount of sparkle in a kitchen . Those brick look tiles mentioned might work

Porous is bad for a backsplash.

Tile. Still trying to get a hot chocolate splash scrubbed out of our limestone fireplace. Can't imagine trying to maintain a limestone or brick backsplash.

I would suggest porcelain lookalikes for your desired look, rather than the real thing. Daltile has a great brick look glazed porcelain called Brickwork that is available in two sizes. https://www.daltile.com/products/stone-look/brickwork
