What boat has the cleanest low speed wake

So tons of threads about best wake, biggest wake and optimal loading of all boats.

With 8&6ye old daughters now starting to ride consistently and being almost time for them to start jumping, what boat puts out a clean, low speed, no ballast wake for the shorties, but still satisfies your intermediate/advanced riders when weighted? Decent goofy side surf wake would be bonus .

My original star is wash to about 20.5-21
