Suggestions for Linux laptop

[Linux for blind general discussion]

I will be taking a Linux administration class in the fall. I wanted to get a new laptop that I hope to use for that class. Does anyone have suggestions?
With the research I did some possibilities were:
system 76 Serval WS
Purism Librem 13 laptop
System 76 Oryx Pro laptop
System 76 Galago Pro laptop

Any help would be greatly appreciated.
