Snapdragon does poorly I think because it's a bet if it works or not. Windows runs things seamlessly other than OpenGL (it can run that too but it's not anything strait forward - needs the gl to dx store app thing) but the other reason is cost. for the premium business laptop most buyers (business) won't budge off Intel even because of the "no one got fired for buying IBM" mentality at the big Enterprises Ive been at.
I will say with my 8 gen 3 snapdragon I'm impressed and also disappointed - stupid thing needs active cooling and I'm pretty sure it's bad enough that it's desoldered or damaged the core or something from heat but also you can't get driver updates for the GPU if you wanted because Qualcomm be the way it do.
Driver update depends on your OEM. Both ARM and Qualcomm send driver updates for their premium and upper highend Socs. The support reaching your phone is on the OEM. Google has started to push direct GPU driver updates starting with Pixel 10. So, hopefully others may follow too.
I've used basically every Windows on Arm machine - I actually quite like my X Elite ThinkPad T14s Gen6, compared the the X13s - feels like they got everything right, that the X13s got wrong
