How would you personally rank the starters of each type from your favorite to your least favorite. For me it would be:

Grass: Sceptile, Decidueye, Rillaboom, Venusaur, Torterra, Serperior, Meganium, Chesnaught

Fire: Charizard, Infernape, Incineroar, Emboar, Typhlosion, Blaziken, Cinderace, Delphox

Water: Greninja, Feraligatr, Blastoise, Swampert, Empoleon, Inteleon, Samurott, Primarina

I know some may be controversial such as having Blaziken so far down the list but what can I say, I like what I like and I don't care too much for Blaziken despite how good it is in battles.
