Silver is better than Diamond to low Masters in their entirety
Low Diamond is full of terrible players with insane egos and horrible attitudes. High Diamond to low Masters is almost the same except with more competency in controlling characters. And due to the small number of players, animosity between recurring sights grow very fast and people will troll each other rather than try to win. Often...
Silver by comparison? People might not play as good arguably but they have great attitudes and mentality and that makes it better in my eyes.
This is from the perspective of someone who's hovered Diamond 3 - 1 for four years now and has been playing on and off on a smurf.
