When it comes to PC OEMs I’ve observed that right now Dell has really good driver support. They’ve got increasingly good utilities for keeping drivers up to date and they’ve been doing a good job of loading drivers and their utilities into Microsoft’s relevant repositories where it makes sense, and that driver support tends to actually last multiple years. I can often pull down a new UEFI update for a 5 year old Dell PC, which is not something I can say of most hardware manufacturers.

So at the threat model of an enterprise org, I’d prefer Dell for that reason alone. Lenovo and HP have tried to implement some of that, HP seems to have given up after building the bare minimum and Lenovo has their typical wonky software that will become good after a few years if they keep investing developer time into it, but knowing Lenovo there’s about a 60% chance some new executive will come in and change direction, and the software will be made increasingly unusable then later discontinued due to lack of use

However for my personal computers, there’s a high chance it won’t even be running Windows so I just buy based on hardware & price alone
