Using different OS as workstation

Let’s say i’m using different OS as my workstation.
How much i be hurting my anonymity if i use some not so popular linux distribution ? How much i stand out on tor network, on server side (when i browsing) ?

Have you seen Anonymize Other Operating Systems already?

When you use Tor Browser for browsing, fingerprint should not differ from other TBB / Whonix Tor Browsers users.
