I did post in the other thread, but I feel like making my case here.
My reasoning is the opposite of most of the posts I've read. Most of the time I think flight is a rather simple superpower, but in this case I definitely like it.
Consider for a moment that everything that you can possibly do with stealth involves people. You can avoid people, spy/steal from people, run from people, but that's it. There are a lot of problems that can't be solved by dealing with people.
On the other hand, if my hypothetical family were in danger, convenient and highly-controlled flight gives me the ability to quickly get them out of most situations, as well as giving me an edge over most people when it comes to stealth.
While invisibility has great power, I feel that flight has much broader uses and shores up its own weaknesses by adding superior mobility even close-to-ground.
In addition, flight would definitely feel more rewarding than mobility for the most part, since a lot of the subterfuge I would go through while using invisibility would not feel very gratifying when I consider that it's usually at a cost to somebody else.
And that's why flight gets my vote. TY for reading. :3
