It's entirely dependent on the bathroom.
My work restrooms are public to the building (shared between the suites on the first and second floors) but I'll sit on those toilets because I know their cleaned regularly and the repeat customer nature of the bathroom means people aren't going to be assholes about peeing on the seat.
If its a restaurant or cafe toilet, I'll vary the strategy based on the niceness of the restaurant or cafe and how clean the toilet looks.
I NEVER sit on portapotty toilets.
