It really depends on the Pokemon you are fighting and the strategy of your opponent. Charizard is weak against Water x2, Electric x2, and Rock x4.

Charizard is a Fire and Flying type pokemon.
There is no specific best berry but depending on the Pokemon you are using certain berries can pull a victory out of nowhere. For example say you have heracross verse charizard your already thinking charizard will win but you use rock slide to beat it but charizard doesn't faint and uses fire blast heracross doesn't faint but it will on the next turn, also heracross is slower than charizard so charizard will beat it because of its slower speed. But your salac berry activates and you use rock slide again and defeat charizard.
