Framework if you have the money. Otherwise Dell.

Every single lenovo product that isn't a thinkpad is a nightmare to repair. Their keyboards are plastic rivited in place, so you have to swap out the entire top half of the chassis to replace the keyboard. I've had unending issues with their ideapad line motherboards. That laptop went through two replacement motherboards and was out of commission for months. The build quality of their all-in-one is terrible and you have to do a complete disassembly to add ram. I say this as someone who had to do small business IT. I have fixed 4 separate models from them and each one had terrible build quality. Also, dont forget about the superfish scandal.

Asus is fine. I and several friends have had many of their laptops. Though one of my friends had the motherboard on his TUF line completely died out of no where.

Dell's build quality and repairablitity remains solid. Easy to source replacement parts. Good Linux support. I've had the fewest problems with their hardware

Also checkout framework if you have the money. Good stuff from them. Really how laptops should be. Each part has it's own qr code so you can immediately identify it and get a replacement if needed. It's amazing.
