Snorlax to Power Up

112 candies - why not both?

The 98 IV one will be good for slotting high up in a gym, and no Snorlax is a bad defensive Snorlax. His worst moveset is still a better defender than any other pokemon not named Lapras.

The first one is definitely worth powering though. You have more high end defensive pokemon and need an attacker though? Which pokemon can defend but can't attack? I understand the opposite but not this order - outside of Snorlax I don't find any good defender to be a weak attacker. Slowbro, Wigglytuff, Clefable, and Poliwrath are clearly better suited for defense but still do okay, and Vapo/Dragonite/Exeggutor/Arcanine/&company are all better at attack.

Earthquake still does quite a bit of damage and lick generates the charge very fast. It's already a higher level and you mentioned needing an offensive Pokemon.

Snorlax may be "better"suited for defense but it's versatility and excellent stats make it a great attacker. Although you may want to leave it a lower cp for attacking.

You have so much candy you could invest some in both. No matter what choice you make it is the right one.

Definitely the 1st one. It's a very good one.
Dont waste candies on the 2nd one. Its the worst moveset possible. Use it as it is now as an attacker or put in a gym where pokemon are below 2200CP

Go for the first one. In the future, when you have a lot of good offensive pokemon, you will regret of investing on a attacking Snorlax.
