Of the two, I like Google Earth a lot more! The ability to flyover areas let's me see places of interest from above. If something looks interesting, I can switch to street view and explore. The only thing I like more about Wander is that you can look back at older photos of locations. I lived in Japan back in the 80's, but the house I lived at was torn down in 2016. I can still see it on Wander by viewing older Google images, from before 2016.
Actually, if you can afford Wonder, it is really worth getting both! However, yes, Google Earth is more involved as an experience, is great! And is free!
Show don't tell! You should really be showing us the experience not telling us about it. This video should just be your conclusion not the whole of the videos. We need to experience it and decide for ourselves. Show us what they do. It's a video! You have all of the equipment there to make a proper video.
