I guess Fire Types would be my 2nd Favorite a lot of my other favorite Pokémon and one I often use are fire types: Arcanine, Magmar/Magmortor,Volcarona,Typholosion, Charizard,Blaziken, Torkoal to name a few.
Ghost
Electric
Grass Types are my favorite starter but not too many of them are good for me to use aside from the first 3 grass starters.
