Some Bujinkan schools spar and some do not. From a street self defense perspective sparring is not the end all be all of personal protection. Personally I spar and in IRT we spar full contact as well as grappling and sparring with weapons. Some Budo Taijutsu Dojo that I know of also do this but they are not the majority by any means. Personally, the most realistic form of training for self defense with pressure testing is to do Scenario Based Training. Walk through a scenario and then pad up and have at it. (it can go anywhere the participants take it) Scenario Based Training is essential from a self defense perspective in my mind. Hard contact with potential grappling and or working to escape, etc. Quite a few Bujinkan schools I know of have a bit of this within their curriculum.
Some people will simply not like the training within Budo Taijutsu. (just like I or you may not like what they are doing) With your background in MMA and a desire to learn it probably will suit you really well. Many of the pioneers in the Bujinkan came into it from other systems and or military, police training, etc. They not only enjoy it but swear by it! Since real world self defense revolves around weapons/tools and this is a system that deals with them then it makes sense that people in real world dangerous occupations like it!
Hope that helps!
