Messi for me, no question. His ability to read the game and make those impossible passes just feels like a different level of magic that I personally enjoy watching more.
I get the appeal of a slow grind but honestly I find that stuff more stressful than fun. My biggest win came from a complete degenerate yolo on Plinko and yeah the math says I got lucky but that rush was way more memorable than staring at blackjack charts for half an hour.
