One that reliably goes to sleep when i close the lid and then wakes up again when i open the lid.

Wifi that works... Audio that works... Plugging in and out external monitors that work... Netflix/Youtube in HD without burning the cpu and draining all battery

Basic hygiene essentially.

I use linux on a laptop every day for the past years and have tried Dell, HP, Lenovo, Asus, Ubuntu, Arch, Mint. Lately things are working, but only most of the time, never really really 100% as a Windows/OSX machine does. You always have to live with those 1/20 times sleep did not wake up or oh time to reinstall pulseaudio again for microphone to work.
