Stand. It's been hella cold here lately, and the toilet seat is freezing! I also feel kind of bizarre standing to take a pee in the women's room, so I will use the mens, unless it's a bathroom that's single only and I'm with my boyfriend, in which case I'll usually just use the womens and then sulk about it.
I've used medicine spoons, sanded off medicine spoons attached to hose, the Pstyle and the Travelmate, the 'hand' method, have a Shewee coming in the mail, will eventually pick up a Whiz also. Once I've used/determined the pros and cons of each, I'll probably make a video or something talking about them and visually comparing them.
I feel you on the clumsiness thing. When I'm trying to adjust a prosthetic, undo my pants, get the thing in place, hold this with one hand, hold that with the other, fiddle, gah! I only have two hands! So for the first couple of weeks, yeah, definitely not time effective and also, pee'd myself a couple times. But since that first week I've been almost exclusively standing with no leaks whatsoever. Now if only I could do it through my pros without having the thing smashed BETWEEN my thighs! (Not right... Just... So anatomically not right to have balls in your crack and willy bent at a downward 90 degree angle!)
