I know OP's rules say no picking one of the three already, but these are such good points I can't help but agree. I'm also biased from years of using a PlayStation controller. Even though I haven't owned a PS console since PS2, I've still been using the PS4 & 5 controllers for PC gaming.
I think legibility and avoiding overloading symbols is top priority and the PlayStation glyphs achieve this admirably. On a pettier note, I've never liked seeing a prompt with a big, red B button pop up on screen telling me to do something, it's very immersion breaking. While the PlayStation prompts aren't exactly diegetic themselves, they're at least less non-diegetic I guess, if that makes sense?
I won't argue symmetry vs. non-symmetry of control sticks as I don't really think there's a correct answer here, it's very preferential. I obviously prefer the symmetric, but I think there's a reason the DualShock has undergone only minor changes since it was first introduced in check notes 1997?! JFC, that's almost 30 years ...
Hope you enjoy! It's getting referenced so much these days, I think I'm due for a reread myself.
