Yes, Childe International is the best multitarget team in the game (as long as we don't consider 5* C6) because Tartaglia brings a lot of Frontloaded Damage and a lot of hydro application that allows Xiangling to vaporize all his pyronado even if the pyronado hits twice. In terms of damage and speed Tartaglia is the best option in international in many situations, however Xingqiu always brings damage reduction and prevents you from dying from a strong hit (like in the 12-2-2 in the video).
