I dont know anything about faucets other than using them. But not all faucets are the same. The mechanism, the design tolerances, the materials, the granularity, smoothness and its longevity can vary by a lot.

Grohe used to be amazing, i am not so sure how things are nowadays. I’ve heard enshitification has hit them. If you own a house, a faucet is something that you will use for decades, even centuries(your descendants). Something that you will interact with many times a day. It is worth spending a bit more money to get something good.

Either is fine but i strongly recommend going for amd, especially an x3d one, like 7800x3d(if you care about gaming).
