Yes, both machines are not too recent (by now I'd expect to find them for cheap on ebay) but they support my workloads more than well. I work in ML and they're fine for general Python programming and exploratory data analysis. I spin a VM for anything that requires more memory/threads.

I'd would probably buy a beefier laptop from Tuxedo Computers or Slimbook if I needed more performances hoping to win the Clevo/Tongfang QC lottery (my T480s was fairly expensive in Italy 3/4 years ago).

So I guess that it ultimately boils down to the type of workload that OP deals with.

edit: poor grammar
