I film a lot of the girls now. It becoming a requirement lol. I just use my phone but have switched types a few times to get a better pov feel mostly.
I was doing it by holding it but ive moved up to a tripod that i bring along. A girl i see lets me use her equipment and having a tripod with a light ring is a game changer. Ive really up the quality of my videos.
Ive tried drones for other things and they just make too much noise.
Selfie sticks are ok, just get a nice one.
Those hand held cheap gimbals off ebay work fairly well but tie up your hands too much. Im all about hands free.
