I would say Charmander since your attacks available to beat Brock are all not very effective, and then misty would probably kill you, then if you had charizard by Lt Surge though you can easily over power him its electric attacks could fry you.
definately charmander due to the bigger majority of gyms being harder to take out with fire type moves
Lol whut?
Rock <-
Water <-
Electric
Grass
Psychic
Poison
Fire <-
Ground
Those are the 8 gyms, and Fire is only not very effective against 3 of them.
Not only that, but you can catch pokemon to get rid of the problem (Pikachu for Misty, any water type for Blaine, ect.)
Charmander is only difficult for Brock, but that's really only because you'll be slowly chipping away HP with scratch and ember.
