Since its dark it has a usage in the raid meta.
But tyranitar outperforms it.
the need to use rare candies,
66k dust,
i would say no.
Keep it and grind Absol raids and power it up with regular candies as a trophy though. I hatched a 98IV snorlax, took it to lvl 30 at a cost of 66k dust+66 regular candies. No real need for more defenders, but its snorlax with sweet IVs.
