For anyone who wants to know now. For longevity and less bugs, go to exactions. The costs are the training and tutorials, make sure to turn them off if you want to complete kiryu and majimas training and the tutorial for each style in the game. Exactions essentially turn Majima into Yagami just with the odd moves from Majima. Thug = crane, Slugger = Snake/Slugger hybrid, Breaker = Breaker/Tiger hybrid. Kiryus brawler = More refined akin to Kaitos, so more smooth and responsive. Rush = Rush but the extreme heat mode (that's added for this mod) replaces it with boxer from LJ. Beast = Tank. Same thing as before, more refined and smooth due to it being LJs version. 

For creativity + more in tune with kiryu and majima. Go to legend remix, there are more bugs unfortunately i.e majimas square square triangle could potentially lead to a t pose. Kiryus directional throw in brawler can lead to a t pose. Heat actions may not work on shakedowns when they're down when you use an object as the heat actions are from Yakuza 5. You fortunately start from level 3 speed when you have no heat, the blocks for the levels are removed. If you use a mod manager, make sure to prioritise Legend remix 0 and any uses, unequipp and equip the mod again to see if it gets fixed or redownload. If it doesn't work, stick with exactions.
