The Bible Students General Convention in PA is very much like JW conventions, suited guys standing behind a podium talking iffy religious doctrine like it's God's pronouncement. The Dawn Bible Students are about as cultish as the WT, and yest, I'd even dare call them Russellites due to their insistence that somehow Russell was God's messenger.
Then you have the non-cultish Free Bible Students who don't believe the 607bce date teaching and rejected all the Russell pyramidology crap.
The Free Bible Students Conventions, held in Wenham MA, at Gordon College, are a much more informal affair, with lots of singing, and family focus, sessions for kids and break out / small group sessions where every one takes part. The Free Bible Students and Berean Bible Students broke away from Russell over a hundred years ago and have been holding these conventions all along once every year.
