Do any significant disadvantages of Privacy Badger stand out to you, contrasted with uBlock Origin? The biggest problem I can think of is that uBlock Origin will immediately prevent me from loading content that could be dangerous, while Privacy Badger has to visit dangerous content enough times to learn to block it, which is less good for security.
On the other hand the big advantage to me for Privacy Badger is that it doesn't depend on manually-curated lists. uBlock Origin nicely wraps the block lists but when it comes down to it you are giving control over your browsing experience to the random volunteers building these lists, which, who knows? Though I'm not accusing anyone of anything.
