[MCU] Who was more dangerous; Ego or Thanos?

Ego's plan would have been more detrimental to life in the universe, since it would have destroyed everything and remade it as part of Ego's grey goo.

But if you're talking raw power, Thanos with the full Infinity Gauntlet was stronger. And (endgame spoilers) >!Time Travel Thanos did plan to strip the universe to its atoms and rebuild it to his liking, which would have topped even Ego's plot.!<
