I'm currently on the southern part of K54, but overall, almost every tribe in the K looks fairly awful.
(Rank 1 in K, Rank 1 Overall, 60 members) - My Rating: 5.5/10
They are currently the number one tribe in the K (and in the world), and they really do have a decent spread. They're rank number 2 as attacker, which I would normally pin as a bad thing early one. However, I don't find it surprising and don't think it's indicative of their skill, since that's probably just a bi-product of having 60 members who are almost all farming at this stage.
However, the reason they are #1 is because of their recruitment strategy. It appears to be, recruit everyone and kick those who fall behind. They've basically maintained 60 members since the start of the world, and have 138 tribe changes currently.

The rank two tribe in the K. They have a completely awful spread with just a massive cluster in the center of the K. 106 Tribe changes which is fair for this stage. Currently rank 13 in ODA which is also fair.
Low expectations, will fall soon.
(Rank 3 in K, Rank 20 Overall, 60 members) - My Rating: 3.5/10
Bad spread but better than SHOCK's. 68 tribe changes which is very low at this stage, and could be good or bad. Looks to have decent leadership and very low ODA (rank 44)
Doubtful of their success because of all the dead weight they managed to recruit. Won't last until late game but it wouldn't surprise me if they last a month or two.

They are an interesting tribe because they currently hold all three of the top 3 players in the world. That doesn't speak much for their appeared quality though, because their spread is absolutely godawful with up to 14 members in a 15x15. Don't know anything about the leadership, just that they aren't recruiting properly.
No chance of success.
(Rank 20 in K, 71 Overall, 14 members) - My Rating: 3.5/10
They are a low member trip in the central part of the K. They aren't clustered too badly and will have room to grow, and about half of the tribe seems to know each other and have joined before the world started.
Don't know too much about them though.
Other than that, CHEER!
(8 members each), GNOME
(12) and XMEN
(7) looks like they could end up being decent, but they're too small and it's too early to tell.
Anyone else in the K is just rated 1/10, or they are under 5 members and I cannot bother.
