I've heard (word on the street, naming no names, reliable source) that competence in Judo will let you mop the floor with a 'Jitsu' practitioner. I've also heard that they'll ban you from entering tournaments if you're a judoka unless you gain a certain amount of grades in their system.
Not exactly true, or at least it wasn't as of a few years back. TJF nationals was your chance to randori and the idea was that you would compete against people approximately your level, Judo guys had to be members of TJF to compete and if they did they competed at a level one up from their Judo grade because they trained for Judo randori full time whereas TJF does cover Judo randori but it's one of about seven areas so obviously they aren't going to be as good at it (Nor do they pretend to be).
Having said that though, I would have to say that the overall fighting ability of a person will increase more in Judo than it will in TJF, but then again, that might in part be down to the type of people drawn to Judo and TJF.
