...it depends.

If you need to get to the airport and must know if a road has been recently re-routed or that traffic is clear in order to make your flight, no (unless there is a live traffic feature I have to seen yet?...)

If you're well-being isn't dependant on avoiding minor disruptions, then absolutely!

I absolutely use it as a daily system and contribute to the network when I notice something is missing.

I use it for biking/walking in my home city and really like it for that purpose.

I'm not using it when I have to take public transport (it usually gets the correct route, but doesn't include departure times) or if I'm looking up locations in other random parts of the world, as I'd have to download that area first.

It's great for cyclists, hikers and when in a new city. It's also good for in-car navigation, but no traffic support yet.

Google Maps has better navigation, but Comaps and OM have better management of bookmarking places. The search on Comaps often suffers, so I mainly use my bookmark list searches for stuff. I haven't used OSand because it was so clunky and horrible right off the bat, but supposedly that is a way to access OSM bus routing. Considering how unreliable many municipal transit network apps and their Google Maps integrations are already, that's just to be expected tho. Huge benefit is being able to more easily export that data for use in Emacs Orgmode, as with other log files, but that's kinda complicated

Google Maps has an insane amount of resources & the time economy of FOSS devs is totally managed by nonprofit donors and/or also overlapping with larger tech employers

I'd love to be able to break free from The Goog so I tried it, but it doesn't appear to reroute based on live traffic which is a must-have for my commute.

It'd probably be far better if you commuted in a less traffic-sensitive way, e.g. on foot or by bike, though.

That's depends, what's your primary mode of travel?
