Personally I would join House Redoran, however, it might be a good idea to investigate each house individually in order to decide which you like best (particularily during the Hortator quest in the main storyline). It is also my understanding that each Great House offers you a stronghold (though I could be wrong).

PS There are codes which allow you to join each house anyway :P
