I think that along with ballet, Simoni knows how to break dance and incorporates that into his fighting style. Unlike Orange (and possibly canon Rise Mikey) who uses razzmatazz as a way to prove that he doesn't need to be babied, Simoni just does this because he gets too bored and likes to spice up his attacks. Makes him unpredictable y'know?
Now that I think about it, Blue would probably be more proficient in fighting right? Since he's in a family full of incredibly talented people, Blue feels incredibly insecure and downplays achievements even when they were well earned. In this Au, he would probably train a lot more to "compensate" for his "lackluster" abilities. Similar to canon Rise Leo, he's a great strategist and can smooth talk his way out of most problems but Blue doesn't value this skill a whole lot.
Because of this extra training, Blue probably rivals DaVinci in combat proficiency. Vinnie isn't a slouch either and despite the more calm and maybe even playful demeanor in this Au, DaVinci is just as committed to training as his canon counterpart.
