I have Lenovo which offers a great on-site support, have been using Thinkpad X since X201 or something and now am extremely happy with Thinkpad P14s with 42G of RAM and especially an AMD Ryzen 7 Pro with 16 threads and which provides much better 3D hardware than what Intel provides, and still much cheaper. Only problem is battery that is not as great as Thinkpad X when you can upgrade to a double battery in addition to the one that's inside the laptop itself. I use Linux.
