The 80. Not because of the difference in level, but because this one has 15 in attack. Personally I always go for the higher IV specimen, but realistically Dnite is offensive, not defensive, and 2 Stamina isn’t too huge anyway. If you like the 84 for it’s better overall stats go for that.
But you’re sure these are the ones you want to invest in? If it’s been too long and you don’t have any other dragon attackers, then they’re not too terrible. Otherwise I would hold out
