Excalibur is the best at hunts.
There's a server-wide effort with a bunch of leaders constantly tracking the time-of-death data and pretty much the entire server being in one big Teamspeak group and there's absolutely zero FC feuds.
Phoenix is pretty great as well. There's a few people that do their own thing and have been blacklisted by the big Hunt LS's but missing out due to an "early pull" (can there even be such a thing? Its open world content) doesn't bother me at all. The best hunt LS on our server runs the show and I'm lucky enough to be in it thoigh.
