The scaling for team 7 in that fight main came from adult konohamaru
Boro whole thing is that he is very haxy, not big on the stats
You can argue that unstable boro is > delta in term of stats due to statements of him being more dangerous than her, but i dont like that interpretation as it would imply team 7 in base (and off guard for mitsuki) and beaten up after the fight can survive six path level of attacks
So i would just say that boro is stated to be more dangerous than delta due to his regen + poison hax
