After a lot of market research, I ended up with this one, and I am completely satisfied! It is silent, has a nice finish, and is of high quality... regarding the scratches, I will say this: I don't think you will find a stainless steel sink on the market that won't get scratched, so it would be good to get some silicone protection for the bottom! In the case of this sink, it is quite resistant to scratches, which is why I give it 5 stars!
