First off how do you hold rank in Judo without ever doing Judo? What organization is supplying you with that rank, or are you instructors just awarding you rank in both?
The curriculum between the two is pretty different, having studied both exclusively on their own.
Also being a student of Jujutsu you should probably spell it correctly.
First off, Judo uses a Gi instead and doesn't normally wear hakama which is a pretty noticeable difference.
Strikes, weapons works, and small joint manipulations are a pretty intrinsic part of Jujutsu
As is forms, which Judo spends very little time on.
The throws are totally different, Jujutsu throws were designed with an armor wearing uke and tori involved, hance they are much larger in scope and motion. Using strikes is a major portion of the throw with Jujutsu, it heavily favors as their form of kazushi. The big circle motion of the throw also takes some of the leverage aspects out of the picture. Most of Jujutsu throws rely more on momentum then leverage, as such some of them require a good bit of strength to pull off since the initial idea was that momentum in armor worked against a person. Judo throws tend to be smaller in the circle, and work heavily off the use of leverage along with the momentum, no nearly as much kazushi is needed.
For example many Jujutsu throws do not require Tori (the thrower) to bend their knees heavily or focus on getting below an opponents center, being in armor this could be difficult. Whereas Judo a great many of the throws are done in a small tight circle with dropping your obi below your opponents center of gravity.
Additionally, there is little to no matwork in Jujutsu as there is in Judo. I would seriously question anyone who gives you rank in Judo that matches your Jujutsu rank if you have never done Judo, or done Judo randori and the like.
That is also typically a big difference is the frequency and time spent on randori between the two styles.
Additionally, what you might be thinking about is the difference between Nihon, Goshin and Gendai versions of Jujutsu. While many of the original versions of Jujutsu do include the type of techniques you list, most of them are taught in a way that allows you to do it safely, while also showing how to modify it. Judo does this as well, but the amount of time spent on the modification usually is low.
Jujutsu does have "nasty bits" and ways of using the throws, but again keep in mind this was done with armor in mind, most of the "nasty bits" in the curriculum require modification to work with hand to hand situations are done today, while yes any throw can be changed to be lethal (in Judo you just don't pull the string on half of throws and you are dropping a guy on the base of his neck.)
I would question the place and style of Jujutsu you are learning, the 3 or 4 different styles of Jujutsu I learned were vastly different than Judo, because they focused heavily on the stuff you can't safely practice, and spent time letting you get the basics of the throw safely, then telling you how to modify it, and all of them revolvled heavily around momentum and using striking as a set up and part of the throw.
