Favourites - Queen's Quest & Oedo Tai (yeah yeah there I go again with the Joshi's right off the bat :P). I cannot think of a single member of these factions that I don't love. Seeing Queens Quest coming out all garbed up in their regalia always makes them feel like final bosses, and watching Natsuko Tora always wanting to destroy them is just good shit.
Also for younger me: DX. Early DX, middle years DX, hell even Old Men DX™. The little kid in me just starts jumping when I see Hunter/Shawn and the others yelling 'suck it.'
Least favourites - House of The-Fuck-Evil-Pissing-Away-His-Career-In-This-Shit-Faction-For. I genuinely do not remember anything Evil has really been involved in since House of Tomatoes started. My brain is a void when I try and recall. And that's from an Evil mark.
