Personally, I’m a fan of authentic IBM Model M’s, and as long as the machine has a PS/2 port, then you can use those from MS-DOS all the way up through Windows 10 because a keyboard is a keyboard as far as its concerned.

However, PS/2 to USB adapters don’t tend to work too well with Model M’s because of their higher-than-usual power consumption.  There are solutions, but specific adapters have to be used. 

If you need a USB keyboard, there’s always Unicomp’s Model M replicas.  They took over the rights and tooling to make new keyboards in the same pattern, and they tend to work just as well.  Plus, they have more options than the original ones.
