I do. On my phone it's so much more performant than the extremely bloated google maps and on my mac I just don't bother opening a website to view maps.
It's also much more usable than the UX mess that is Google Maps. I don't use either enough to specifically triage what's going on with Google Maps - all I know is the last half dozen times I have opened Google Maps I get annoyed quickly and fumble my way back to Apple Maps (on iOS and MacOS too, come to think of it) where it seems easier.
I haven't paid much attention to what the issues are, as I expect a mapping app to be intuitive enough that I'm not thinking about anything but finding whatever I'm looking for.
