Good or Should I keep hunting?

[Nue]

I was informed that Charizard X was in game and Charizard was a original favorite to use back in the day so I reset and got this little Jolly natured guy.

 

Ivs are one of the best I have ever gotten but most people have said adamant was better but he will have tough claws so what are your thoughts on him?

If that is your starter, you'd probably be better off with a nature that doesn't reduce SpA. It will be quite a while before you can use him as a Charizard X, and besides you'll be able to reset the nature to whatever you want later on. 

That said these are fairly decent IVs. 

 

Charizard can also be found in the wild (very late in the game), so eventually it will be possible to try again for a better one if that is a concern.

Additionnally, you will need Dragon Dance eventually, which Charizard can only learn by breeding (with an Altaria for instance). So, you'll have to use another Charmander anyway.
