I’ll start of rambling some subgenres
Excentric juggling like Bobby May, offbeat, shoulder play.
Symetrical repeating patterns linked together, as Jay mentioned in his TED talk “American juggling” or sometimes “old school”, running without stopping.
Combination tricks/multi tasking, characterized also by the build up and down of the tricks which expand
Ladder progression performance, doing a series of L backcrosses, than R backcrosses, than doing a run. Similarly, start with 3 props, go to 4 , 5 6 etc. like Anthony Gatto
Floaty vs spinny juggling, for example where jugglers prefer to catch their club on the handle
Mentally challenging juggling. Easy throws in a complex pattern. Luke Wilson’s 3 club full/half patterns.
In hand action. All the patterns take place in the air, or a big part of the tricks happen in 2’s, catches, rolls.
Perhaps 3 axes on the scale could be the the Body vs Pattern Vs Time thing. Usage of body, 0 when static (the average 7b juggler), max when full on dancing/body throwing. Patterns. 0 when cascades/fountains, max when complex siteswapping mills mess ish multihanded passing. Tme, 0 when repetitive, every trick at the most comfortable pace, max when mixing fast, slow and unexpected.
