I suppose it depends on your Lenovo series.

I have been using exclusively T and X laptop for the past 20+ years and it always worked perfectly. There was a time where the battery life was better with Windows, but maybe only 2 or 3 years "in-between". Nowadays, the hardware support is for me a non issue.

I had a T14 AMD for 8 months or so last years and it was death by a thousand paper cuts. Wake from (S3) sleep would not work well, e.g. the trackpad/point would often not come back up. Sometimes the GPU wouldn't wake properly. The fingerprint reader rarely worked. Bluetooth was very flaky. Battery life was much worse than Windows. I had a Lenovo USB-C dock. However, Linux configured the lanes wrong, making it impossible to use 4k@60Hz through the dock (worked fine on Windows).

except the fingerprint one because I don't have a fingerprint reader, I had all these issues on my windows laptop

My experience, also using T and X series laptops matches yours. Some issues with resuming from sleep a long time ago and with firmware on a docking station once but otherwise only one gripe: I've never been entirely happy with the fan control. I found in the end with my T440s that leaving it to the OS worked well enough. Previously, with older X series machines, I had to both try to optimize and also ended up replacing fans.
