My only gripe is one that exists for most universial systems. Which is they allow you to play any setting, but if you try to mix them then they start to run into more and more complications. Especially when you try to mix high and low tech. Or trying to put magic vs machine gun.
Though I will give Savage Worlds a benny over most universial systems. A guy with a gun will probably destroy a medieval knight. But if the melee build gets into melee range the tables do legitimately turn. Long-Arms can't fire in melee range, sidearms will have to test for parry for attacks, and the melee build will have high parry well a gunner will have a parry of 2.
Also of you really want to narrow the gap and dip into anime territory. Then Supers Companion can really help you there.

Also the system sucks for traditional boss fights. Though some see this as a good thing, and I don't think the game was ever designed within the scope of Goku fighting Brolly or anything like that.
