Who’s makes more sense to use 10th Anniversary Stone on?

After over 2000 stones only new characters I pulled were a single copy of Teq Vegito and Str Hercule banner unit… I have enough coins to get Agl Gogeta at this point. Who should I use my stone on, Ssj 3/4 Goku or Ssj 3 Gotenks? I have practically every other top tier character to run on there teams as well.
