I tried to go back to Linux in one of my laptops recently (old x220 I want to use for ECU programming). I used to be a gentoo user before their wiki disappeared. It seems to me like Linux is going through a growing phase with several growing pains. Why are my graphics working worse out of the box with common Intel Graphics than back in the day? Bluetooth is a terrible experience. Wifi doesn’t work 60% of time and I don’t know why, the UI won’t tell me. These used to be issues in the past but I figured that 15 years of progress would’ve changed. However I am aware that all these problems are open and it’s up to me to fix them and I feel no entitlement or have any expectations out of a free and open product. I wish I was better equipped to assist in fixing them myself. Unfortunately I ended up putting Windows back in that laptop. For a while I used it as a hackintosh and to be honest it worked better with High Sierra than it did with Mankato or Ubuntu.
