Being in the UK, I use 25fps. 50fps if I wanna go for that super-slick motion, or slomo. But I don't really like the look of 50fps/60fps.
Working in After Effects for animations I do get the choice to create something at any frame rate, but I prefer to stick to 25fps.
If I'm on DSLR, I'll usually shoot at 25 unless I think I could slomo it. Then I'll go to 50.
Problem for us is that all phones and GoPros are shooting at 30fps. So if I've got a combination in the same vid, I'll pick a frame rate that matches the most commonly appearing clip.
Then there's Variable Frame Rate from phones... (shudders) ...
