How do you deal with all the pee splatter? Or do you piss on the sink? Or are you a dwarf?

Pissing while standing is only ok when a proper urinal is available. Pissing in toilet while standing imparts too much kinetic energy on the pee, causing violent splashing. Yes, even if you aim at an angle. And aim will always falter at the end anyway with decreasing water pressure...

I used to always stand. Once I realized that even with perfect aim, urine droplets will find their way to the floor and walls, I stopped. My toilet never smells like urine now, even if I haven't cleaned it for a while (which is rare).

I do about half and half. Especially in the morning or in the middle of the night I sit. Don't have to try to aim in the dark or when I'm half asleep.

I suspect also the men who are married with families tend to sit more than single guys.
