In this case Teka is fine. But note that stainless steel requires more maintenance than granite sink like Blanco. It will scratch. It will have ugly water stain if you dont wipe down on the sink. Good thing is if you drop your glass it has chance of surviving. Granite sink no chance

I have a grey metra 9 in my old house. New house is using anthracite (black see photo). The water mark on Blanco is much less noticeable than stainless sink. I am having a Kraus stainless sink in dry kitchen and have to wipe it down every time after use. It's a pain.

Metra9 I don't do that. Blanco recommends that u do but I find it is not required. The photo below I took after I washed my plate just now
