If i'm not mistaken, that game is one of those ridiculously hard to emulate games. Haven't played it, but youtube shows that even a Snapdragon 888 has trouble playing it full speed.
Maybe the newest Dolphin versions boosted the performance considerably.
I'd say go for the more powerful device. While coming from a 835, any of the two choices will make a big difference, 865 is noticeably more powerful than 855.
Don't know how agressive the governor is towards power saving in Samsung though. I upgraded from a OnePlus 7 (855) to a Rog 3 (865+) and there's ~ 40% performance gain in most emulators.
