TBF I've only owned T and X series Thinkpads... I don't know that everything Lenovo is good. My partner had an Ideapad which was terrible.
But the X220, X1 (various generations) and T series... all of these have been incredible. I've a 12 year old X220 which is still going strong, and that's just ridiculous. It's not my daily laptop (that's an X1 gen 8), but I do still use the X220 for debugging network things (it's got a built in ethernet socket) and as a remote console to a lot of my home and remote networking stuff. I've continued to acquire new laptops due to work, etc... so of course I use the newer models more often, but that a 12 year old laptop is still rock solid, keyboard great, storage great, speed great, still runs cool enough... this is just something else.
Also have a Dell XPS, it's also shit. Unfortunately was one of the batches a few years ago which included a chipset whose Linux drivers were not great... so it stayed a Windows machine. It's really garbage, issues with almost every part of it. Considering this is their premium line it's terrible. The keyboard, storage and mainboard were all replaced in the first 3 months.
Note though, that it's actually doing better than the only MacBook I've owned. That one was out of service for months and cost twice as much.
The only reliable laptops I've ever owned have been Thinkpads, and this even includes the very recent generation.
