They are all good. I don't have any preference over Xbox Achievements or Trophies. Steam Achievements could do with having a score/tier and a better way to show them off. Would prefer if the Steam Level on your profile was based on achievements and not trading cards.
But I find all forms of achievements very useful as it's basically like a gaming diary that is automatically recorded. I go back and easily look at what I played, when I started it, when I finished it etc because it's all recorded in Achievements forever. If it wasn't for achievements I wouldn't remember half the games I played last year, which is why I probably can't remember half the games I played on the Switch.
Don't even need achievements really Nintendo. Just a badge you unlock on your Nintendo Account when you complete a game for the first time. That would satisfy me. One "achievement" per game, easy.
