I do this local mapping, and I also use StreetComplete.
I find it's not one of the other, it's "Why not both?"
e.g. new coffee shop opened down the road? I'll take a picture of it on my phone, go home and open https://www.openstreetmap.org/, click "edit" and add it, along with info from the phone photo (Shop name, Address, phone number, and a website if I can find one).
The next time I'm nearby, StreetComplete will prompt me for other key info such as opening hours.
They compliment each other.
On the one hand, the full OSM experience is much richer than StreetComplete.
On the other hand, StreetComplete is a gateway drug to it, and also a useful accessory to it.
Having a dog means that I can record updates and additions as I walk varied routes around the area.
Updating the map later using its Web interface is very satisfying and much more worthy than doomscrolling through social media (which I don't really do anyway).
