256 tokens is a pretty terrible default setting especially post 3.0. I recommend folks use 4 tokens for new clusters, with some caveats.
When you fire up a cluster, there's no way to make the initial tokens be distributed evenly, you'll get random ones. You'll want to set them explicitly using: python -c 'print( [str(((2**64 / 4) * i) - 2**63) for i in range(4)])' After you fire up the first seed, create a keyspace using RF=3 (or whatever you're planning on using) and set allocate_tokens_for_keyspace to that keyspace in your config, and join the rest of the nodes. That gives even distribution.
