I should give a chess one, really.
I'd go for a surprising answer: Vasily Smyslov. He was World Champ 1957-58, but his style was to generate a smooth game. He had an elegance in his endgames (which he was famous for), but his attacks swarmed, with all the pieces working together, like a wave towards the king. I know most don't follow chess, so I shalln't post about him here, other than to say I'd put his beauty above Fischer, Kasparov or Carlsen.
