It heavily depends on your area though. It's often way behind Google Maps, in every populated place I've tried it in the USA. (Businesses are years out of date, roads are missing or incorrect, etc.)
I do contribute to OSM, but day to day I find Google Maps + Alltrails + Trailforks to be more practical (all paid, closed source, but high quality data).
Google Maps also has free offline tiles. Those other two have paid offline maps, but it's worth it to not have to always wonder if your map is accurate.
When your phone can “hear” a cell tower (and thus thinks it’s online) but doesn’t have enough signal to get any data, apps like Google Maps and Gaia will often hang instead of showing you the downloaded map data that’s on your phone.
Put your phone in airplane mode to fix that behavior.
