Just concurring with Tony and JKS here... simply put, yes, BJJ definitely does have something "over" Judo and Jujutsu (Japanese), which is a specialisation and focus on ground work (ne waza), to the point that it is developed to a very high level of sophistication and skill. Then again, Judo has something "over" BJJ and Japanese Jujutsu systems (commonly), which is a simplification of a broad skill (throwing), as well as a highly developed training methodology designed to instil a range of attributes from basic mechanical skill through to educational ideals. And, of course, Japanese Jujutsu (and, to be clear, I'm talking about classical systems here, what are referred to as Koryu) has something "over" BJJ and Judo, which is it's historical legacy and link to the past, a definitive mind-set being the goal over simple technical skills, depth of instruction, and more. The question is, which suits your values? That's the only thing that would put one over the others for an individual, really... for you, it might be BJJ... or Judo.... for me, it's Koryu (really not a big surprise there, I guess...). Of course, the idea of "Jujutsu" being a single type of art, or approach, isn't really accurate at all... you could compare BJJ with particular systems of Jujutsu, but you really can't compare it with "Jujutsu" itself... as that doesn't actually exist.
BJJ, I will say, is not a fad. It was certainly an over saturated product in the martial arts community in the early 90's through to the early 2000's (for the record, MMA has taken that role currently, with RBSD seeming to come up to replace that over the next few years), and was definitely the "flavour of the month" for a little while... but, like anything that has real value to offer, once the shine of "hey, this is new!" wore off, the art remained a valid and highly credible alternative when looking around at different arts (to get an idea of what I mean, try to find a Tae Bo class these days.... it was everywhere for a short time, then faded away, and, having very limited value in and of itself, didn't really last... BJJ, on the other hand, has... as have many of the "flavour of the month" martial arts over the last 5 or 6 decades. Let's remember that Judo and Karate were also "fads" in the same way BJJ was at a time.... but we don't question them these days). BJJ was a fad... but it's moved on, and is well and truly past that these days.
