How is account migration on #Mastodon these days? And which servers are most likely to be sustainable while not overloaded or over censored?

I've become increasingly unhappy with what appears to be silent censorship on Mastodon.social, effectively giving cover for war criminals and genocide, so I'm looking for a new server for this account.

I last migrated a few years ago and it was ok. I don't mind losing my post history or followers. Ease and who I follow is more important.
