i don't just mean brands with this. for example my list:
For laptops i always go with MacBooks.
My OS outside of one Mac i have is always Manjaro, at least as primary.
For phones i always use iPhones.
when it comes to computers my GPU is always AMD, and my base platform is always something enterprise, like my current build with a server board and Xeon cpu's.
For headphones i always go with Sony.
As my TV i always use a CRT.
My main computer display is always 16:10. i really hate 16:9... (part of the reason i use a 2011 MBP as main laptop, even though it does not run macOS. it has a 16:10 screen)
