Anecdata, but before going all-in on ThinkPads I thought I share my experience.
For the ThinkPad x13 2nd gen Ryzen I received for a customer project (with the customer not interested in getting it back after the project was completed) it's too early to say anything about reliability, but somehow the touchpad isn't centered properly and I always hit left click when I want right click - it's unbearable and surprisingly bad for a ThinkPad.
Before, I had an ThinkPad E495 Ryzen that worked ok but after two years the touchpad got stuck - the pointless (for me!) construction with touch point and extra mechanical buttons (only acting as barrier) certainly didn't help.
Before, I had my beloved Dell XPS 2016 which however had a swollen battery. Still, I consider it one of the best notebooks I had; gnome 2 and Unity also just got it right.
In the last four years I got five (!) ThinkPad and Dell Precision notebooks for customer projects having battery or memory problems OOTB (the x13 I mentioned above was a notebook that finally worked).
The notebook I used for the longest time (7 years) was a PowerBook G4 2003. I hope my current MacBook M1 will last me about as long, but at least 5 years. In terms of power management, display, and usability, a Mac notebook is in another league compared to Dells and ThinkPads with Linux, it's not even funny. Linux desktops have regressed to the point they have ceased to be usable for me. With the newer MacBooks, I think Apple listened to customers and nailed it; I'd just prefer lighter (non-alu) materials.
