regular aikido is good aswell,requieres more skill than aikido big dojo due to the small ring.
its better as well to practice saves,its important too.
old sambo is basically the mod-before-aikido,it was used around 2008-2009.
taekkyon still my favorite mod.
and i disagree about mushu being skill mod,look,its just "touch for the win",rarely you will really use skill,if want a similar to mushu but with skill requeriments try wushu,joints are hard to break,wrists and ankles do disqualification,but still engagedistance and turnframes.
in mushu the head does not disqualify,only the neck,it can explain the "glitch",as well maxcontacs or the joint is having friction on a wall of boxshu.
