I think you would find a system76 machine to be a good choice overall, but if you are just learning you might want to start with the OS in a VM in windows and then progress before investing in hardware. You can try Pop out there if you like, or even with the live boot option to get a feel for it.
Personally I use my Thelio with gaming and the windows compatibility tools in steam. It works beyond great.
