Thanks, that makes sense. In my town the usage of either one is so marginal I don't think it matters which I use. And even if I decided to visit the nearest city and start from scratch with KartaView, more recent data wouldn't obviously hurt. And I've got time hah.
As I'm just a beginner I don't think a 360 camera is worth it just yet, they are quite expensive compared to regular ones. And I can imagine putting it on my helmet would get some attention from bypassers, unlike a normal camera mounted on the handlebar.
