Why only those two? I have had bad experience with Dell batteries in the last 3 generations of their models (they swell up at a high rate), and Huawei is a bit of an odd duck for support and even being banned from some markets due to ties to the Chinese government.
You can also look at the gaming models if you don't mind the looks, MSI, Sager, Clevo are pretty good, along in line of the workstation systems. Depending where you are from, I like the xoticpc site for how they organize the models they sell, it's easy to see many systems well organized https://xoticpc.com/collections/opt...e=1&tab=products&sort_by=price&sort_order=asc
