Guide to best known green guilds style/reputation?

[Crass]

I'm out of the loop in the P99 guild world. I vaguely recall back on blue that some prominent guilds had a "personality", for example winning-at-all-cost guilds that always made people mad, or social guilds that were known for unique events, etc.

Now I'm learning about guilds governed by super complex rule sets and departments and making use of third party tools. It's like EVE online but in the EC Tunnel.

What's the low-down on major Green guilds today? Maybe keep it positive or neutral to avoid a flame war.
