Both of these manga contain a pretty boy/manly girl couple, and there are some rougher moments in here. The naive heroines get themselves into all kinds of trouble, and their boyfriends have to get them out. If you like the intensity of Ai Ore!, you'll probably be shipping Toki in W Juliet.
B.B. Explosion and W Juliet are both manga about teenagers trying to fulfill their dreams of becoming famous performers and working to find love despite the challenges placed upon them by their circumstances.
W Juliet and Kamen Tantei are manga of similar quality about creative people; in the former, they're actors, and in the latter, they're authors. The level of story-telling and character development is pretty close in both stories, and I think fans of one will like the other as well.
Ouran High School is a prestigious private academy where money and status count for everything. Haruhi Fujioka is a scholarship student at the elite school, and is appalled by the lazy attitude of the rich and powerful students towards their studies. The Host Club is a clear example of this: a group of six attractive and wealthy boys spend their time entertaining the female pupils for a profit. When Haruhi accidentally breaks a ¥8,000,000 vase belonging to the club, they force her to work off her debt as one of the club's members; and to do so, she must masquerade as a boy! Can Haruhi keep her gender a secret from the club's exclusive clients?
The main heroines of these stories look like boys and are friends with at least one bishounen who dresses in flashy clothing routinely. I suppose you could point out that in both cases, the guys do this to entertain an audience. ^_^ Beyond that, there's a strong and secret agreement which binds one character to his or her current lifestyle.
When Fujimaru's father's business fails he runs away once more and leaves Fujimara on her own to sleep in the park. However, Fujimaru's luck changes when she saves the beautiful vice president of the student council from a guy, only to find out that the vice president is male and cross-dressing as a girl. Ryou works for Peacock, a showbiz company, and it's company policy for their actors to disguise themselves for everyday life. Ryou offers Fujimaru a job as his manager because he needs help getting work, and thus Fujimaru must disguise herself as a boy from henceforth. Can Fujimaru fulfill her obligations, defend Ryou, and keep their secrets safe at the same time?
Both stories share a core theme of [sexy&blonde] male lead character being disguised as a girl in order to fulfill their dream to be an actor. Being disguised and going to school as a woman is the condition made by their boss/father. In both, the female main character finds out about the secret and they become closer. If you liked W-Juliet or Penguin Revolution, you'd definitely like the other.
