It looks like SWIM scales better than Raft. Are there well-known production systems that use it?

SWIM is in no way an alternative to Raft, and vice-versa. SWIM is a membership algorithm, Raft is a consensus algorithm. They are often used together. (a SWIM alternative is plain Gossip and a Raft alternative is Paxos)
