Gigantamax Charizard

The blazing pseudo-Dragon itself, Gigantamax Charizard has the safest position among the three Gigantamax Kanto starters. It battles for the crown with Gigantamax Cinderace thanks in part to the latter's higher Attack stat, but Gigantamax Charizard stays relevant with its Flying sub-typing, which makes it bulkier against select raids. Regardless, the damage output difference isn't huge between the two top Fire Type Gigantamax options, so it's still a very worthy investment.

Gigantamax Charizard is locked into having a Fire-type Max Attack. While this seems like a disadvantage, it's actually a fairly large advantage as it means that it can utilize Dragon Breath, a 0.5 second Fast Move, and still drop its nuclear-powered Fire Type G-Max Move.

Another nice thing about raising a Gigantamax Charizard? It can pull double-duty as Mega Charizard Y or Mega Charizard X in normal raids. That said, a Gigantamax Charizard is best utilized as Mega Charizard X in this capacity due to Dragon Breath being an Elite Fast Move.... unless you want to waste a bunch of Elite Fast TMs.
