Best Laptops?

I'm getting into cars and working on them a lot more. With this being said, I'd like to know everyone's opinions on what is the best laptop for diagnosing and tuning cars. Also, what programs do you use for all these? The more cheaper the price is the better, but I don't mind a high price thrown in to see.

I use the HP Spectre x360 13T. It's very good, I didn't have any issues so far.
