Basically, it's the best compromise for you. The Genbukan has much higher enforced standards than the Bujinkan, and has a section of their syllabus refered to as Goshinjutsu (self defence). Bujinkan schools can be great, or can be pretty bad, so it's more a case of check it out first, as there are no enforced standards. But it's all the same arts. The head of the Genbukan (Tanemura) is the cousin of the head of the Bujinkan (Hatsumi), and the former second in command of the Bujinkan (in the early 80's).
As to the site, it's not bad. Not much information there, and the first clip is just a newsreport. The street survival stuff was okay. Check them out if you want, as I said, it's best to visit each school you can.
