OpenStreetmap is improving, and the maps themselves are good.

Its search leaves an extreme amount to be desired. Recently, looking at the path of Typhoon Hagibis, I'd entered "tokyo japan". I was returned a restaurant in downtown Moscow, Russia.

Even direct latitude/longitude searches often fail completely (I've reported this as a bug), apparently if there's no reasonably local specific place record.

Where Google Maps will deal with a vague street + city or business-name + city reference, OSM is completely lost. Even comma-delimited "<city>, <state>, <country>" specifications often fail.

You can report these, and the reports do get attention. But there's a lot of work required of the team.

Almost exactly the same experience. FastMail is definitely worth paying for, the custom domain ability is great and would make switching in future less painful. Firefox has never been better.

Don't delay, the sooner you make the switch, the better. I wish I'd done it earlier.
