Actually, here’s a question: what do you think a bard best replaces, the support nature of a cleric or the general purpose magic of a wizard?
In a PnP game, I play a Swords Bard with the Urchin background. In my opinion, he replaces everything. Others consider Swords Bard to be one of the weakest Bards, but they are my pick for a gish. If BG3 doesn't add Swords Bard, I will go for Valor Bard. And if there is a Warlock that gets the Hex Warrior feature of the Hexblade, i will make what I consider the best Mary Sue gish; a Swords (or Valor) bard with one level of Hexbladish thing and the Urchin or Criminal background.
Most of this is simply that I like Bards, though.
