Treat style choice as a reroll decision
The best Gakuran style depends on your current style, height band, playstyle, and reroll budget. Boxing and Wrestling are top targets, but safer choices can be better when rerolls are low.
Use Basic to learn controls, then compare Slugger, Muay Thai, Karate, Boxing, Hakari, Capoeira, and Wrestling by role. Do not chase unrollable styles as launch targets.
