I feel that I understand Raft and not Paxos, although currently that's simply because I haven't yet tried to understand Paxos. But the reason I am still interested in Paxos is that looking at Raft, it still seems like Raft has a bottleneck at the leader. Essentially, it looks like what makes this distributed consensus look simple is that only leader elections are actually distributed: the rest of the algorithm isn't distributed at all. When I get around to reading about Paxos I'm hoping it will be different.
