Most people will tell you that it's been made obsolete now since (1) it doesn't use behavioural analysis to detect trackers anymore, it just uses a pre-defined list of trackers to block (2) browsers (especially firefox) now have built-in tracker blocking (3) ublock origin blocks trackers by default anyway.

I don't think it hurts to still use it, just as a belt and braces approach, but I suppose it's possible it makes your browser fingerprint more unique.
