i've been super happy with organic maps, but i have to admit maybe 3 possible downsides:
1. in my country openstreetmap is very well populated so i usually find what i'm looking for, but this isn't the case everywhere
2. search is just not as good sometimes - i once typed "gym" and it took me to a place in india. so to find places i still rarely use google maps.
3. there's no proper desktop app yet, or at least it's not widely published - i think it's being worked on, but until it's in the arch repos (the one in the AUR says it's outdated) i'm holding off on it.still, giving google 99% less data is worth the slight inconveniences sometimes for me. also, it works perfectly offline if you download the maps!
