Jubei-chan is about Samurai and 2x2=Shinobuden is about Ninjas; different main themes, but their sense of humour is about the same. They both dwell into the origin and history of these forms, and make fun of it. I think you'll have fun with both anime. 2x2=Shinobuden is really wacky.
The sene of humor in both of these series are of the same type. They are very absurd and often break the fourth wall by commenting that they are characters in an anime or that there are people watching. Both of these series are parodies in a way with Jubei-Chan being a parody of swordsman/samurai stories and Ninja Nonsense being well a parody of ninjas. There are two major differences between these two series I should mention though. Ninja Nonsense is much more perverted in its humor than Jubei-Chan so the content of the humor isn't always equivalent between the two series. Also Ninja Nonsense doesn't have an overarching story like Jubei-Chan. If these two aspects don't bother you then if you've watched one of these give the other a try.

Jubei-chan and Lyrical Nanoha are recognized for their magical girl stylings: an unwilling female protagonist, the wise sidekick who guides her as she takes her first steps into a larger world, and a mystical artifact that's the source of the heroine's power.
But instead of being targeted to the usual demographic, these two shows seem designed for male audiences. Both series feature enough action to keep viewers interested and provide the necessary back-story for enjoying their respective sequels.
Jubei-chan and Magical Girl Lyrical Nanoha are clearly both magical girl series. However, they are both unusual in that they aren't necessarily aimed at a female audience, as are most magical girl series. In addition, they both have superb action sequences and a protagonist who manages to reach out to many of her foes and show them the error of their ways.
