I would recommend the Thinkpads: it's rock solid and used by a lot of Linux contributors, so the hardware is well-supported and the installation is documented
My Thinkpad experience has been a nightmare. I bought a new ThinkPad one year ago and it has been an absolutely terrible experience. It freezes up every 2-3 days requiring a hard restart. I've sent it in to Lenovo for repairs twice and the freeze-ups continue. Every time I send it in I have to reformat my entire computer then reinstall everything only for the issues to persist. I'm about to purchase another new computer because I need a reliable working computer and my Thinkpad failed. Lenovo sold me a lemon. I hate this ThinkPad so much and it was a complete waste of money.
Not all Thinkpads are born the same : you have the workhorse : T14, T15 P14, X13 that are a bit heavy and have very good Linux support and maintainibility, like add ram, Switch SSD, or so. An the fancy ones X1, X12, yoga, that are slimmer, but less Linux compatible and less maintainable.
any particular brands you recommend?
Thinkpad is a Lenovo product line.
Previously it was an IBM product line.
