The main dudes in both help solve the problems of others presented in arc-format. Plus I guess you could mention both are school related comedies with some romance.......but then again isn't everything?!?!?!?!?!?!??!?!

Both have a similar humour style - that same random, perverted, and generally crazy funniness is present in both. Also both are harem in a sense, except that in Girls Bravo the main focus is on a guy, whereas in He is My Master, the main focus is on a girl. Chances are if you liked one, you'll like the other.

Both are Mecha, and both have very intricate stories involving love, death and of course, the end of the world.
