I think, that solver might prefer

over

is because those block his BD FDs otf. But I might be wrong.
I am curious how frequently solver wants to be this turn with 8x?
Also, I agree with None. I am not a spin player, but turn x/r is pretty nutted line. I'd say, that even more nutted than c/c, c/c and donk shove (but people might have some missed draws in this line).
So I'd prefer to call with hands, that can actually improve otr.
