I would set one of each up and take a file and plot it with both drivers.
There will probably be a performance difference with one or another.
I would pick a complexe drawing that would represent everything that you would normally place on a drawings. Linework, hatching, images, excel spreadsheets etc...
That's what I would do. You may find that one is a lot faster or not so demanding on your system and network. Check print spool file size as well.
