lenovo. replaced my old dell precision laptop with a T480 and I’m loving it. dell pros: fast solid gpu for the time clean look came with linux. dell cons: battery swelled up, made the trackpad and keyboard not work. replaced the battery a lot. keyboard wore out well before lenovo chassis screws fell out and then the hinge broke as a result. this is not a thing with lenovo. For your situation 16G may be adequate. But 24 is better.
