It would depend on what your existing fingerprint is. If you're using some sort of rare browser/OS/hardware combination (eg. pale moon/gentoo linux/IBM thinkpad) it might be worth spoofing, but if your configuration is relatively "normie" (eg. firefox/windows/relatively recent intel or amd cpu/igpu)you're probably making yourself stick out more by faking your fingerprint.

The issue is that, especially on desktop, I doubt there are many fingerprints that more than 100 people have, given everything that they test. I would even suspect that most common desktop fingerprints are classified as bots.
