Should I keep this Landorus?

[Vexian]

hey everyone, I need your advice.... should I or shouldn't I keep this Lando I just caught

Adamant Nature

HP 164/164
Atk 159/159
Def 100/110
SpA 118/121
SpD 99/100
Spe 121/121

The first number is the stats of the lando I caught and the 2nd is what the shat should be with max IVs.
So from the info i have Max HP Ark and Spe only SpD is close to max but the Def is 10 low...
