Regarding what it feels like... it can vary from system to system, and from member to member. For me, personally, it's very easy and quick, kinda like changing your focus from one task to another. For others, though, I've heard it's a much longer, lurchier, unpleasant business. (Sometimes taking a good while, comes with a headache, that kind of thing.) So creatively, you've got a lot of freedom there. Considering you're writing a vigilante/hero, it'd make sense if switching was pretty fast... or you might have a specific member or two in charge of the heroing, banking on staying in control until it's over. Sky's the limit, really!
There's also a lot of variety as to how it looks in the outer world. For some folks, switches are so subtle that they aren't even noticeable unless you know them well. We've known some friends whose switches are pretty much invisible. Ours, however, are pretty blatant--even strangers will recognize our voice changes. (Which can be very inconvenient when sometimes we just want to go about our business without being noticed. But trying to wrestle ourselves into a more singlet presentation has gotten harder and harder over the years.)
Cameron West demonstrates switching here on Youtube. As you can see, with them, it takes a little bit of time, and involves some pretty obvious physical twitches and pretty obvious voice and mannerism changes. Kim Noble's, on the other hand, are more subtle.
You might actually have some decent luck going through Youtube; there's a fair few multiples who interact on there (though we aren't one of them) so you might find one of their vlogs.
Yeah, you've got a lot of flexibility here! You could probably play it just about any way you prefer, and still have it be pretty credible, as long as you put serious thought into how the group would run with it. Systems where switching is slow and difficult have different ways of responding to their environment than a revolving door system!
