The V1 has 76 watts of power vs. the AD200 which has 200 watts of power. So the AD200 packs more punch for light output. The downside of the AD200 is it has to be used on a light stand or other type of support while the V1 has the option of being used on camera. That said, off camera flash tends to yield much better lighting. These are two very different types of lighting units though.
The nice thing about the AD200 is Godox makes a bracket that holds two AD200 units together which gives the combo 400 watts of power.
It's called the AD-B2. Just something to keep in mind for the future.
If you are looking to use a flash/strobe outdoors, both of these choices will have certain limitations. If the sun is shining on your subject's face, neither of these has enough power to overpower the light from the sun (unless you diffuse the sunlight with a scrim or block it somehow). When working with the sun on your subject's face (and without diffusing the sun), you'd be better off considering some type of 600 watt strobe. BUT if the sun is positioned behind your subject (or somewhat behind but off to the side), these will work - but it would be best to search online how to get the best bang-for-the-buck with either unit outdoors. And if you are in a shaded area, then either one will work fine.
Maybe @
Horoscope Fish can offer detailed insight for the pros/cons of both units.
