Choosing one

This is quit different but I am so lost on what to do here, I have 3 accounts 2 silvers and 1 gold, I am very confused on which one to play because each has ups and Downs . The gold account his up is well... he is gold and I like playing on it because the players are nicer, more aware of what they are doing but his down is that he doesn't have many champions and it's boring to play the same over and over . The high silver is the best out of them, he has almost all champs and lots of skins and almost reaching gold but has the worst downside , it was banned 2 months ago because me and my friend we're playing on it which means that there is a chance that I will not receive season rewards and I might get permabanned (although I am not toxic or anything but sometimes I say mean things that I don't mean). lastly is my low silver account , the upside it has that it had decent champions and eligible for season rewards and lots of skins. It has no really downsides besides being low silver which is fine but will take time to bring up. So I need help deciding which one do I put my time in grinding, ranking?
