So for things like iPhone cables, I just buy whatever nylon-braided cable Anker is selling now. I've been using Anker cables for years now and they've been reliable.

But for things like TB and DP cables, I don't have any particular brand recommendations. I'm not sure it matters. I just find something with a good rating on Amazon and buy 2 of them. Whatever gets labelled as Amazon Basics has thus far seemingly worked well enough.

When I was having major issues with my first 5K displays I bought a few of the CalDigit cables (https://www.caldigit.com/thunderbolt-4-usb-4-cable/).

Not cheap, but, they work great.

Hmm, so out of curiosity I looked up both, Apple’s are actually cheaper per centimeter than MP, but don’t sell shorter overall cheaper options if that’s what you can use.
