I generally don't dislike starters, so it goes like this:
Unevolved
1 - All of them bar Chikorita.
2 - Chikorita.
2nd stages
1 - Quilava
2 - Ivysaur/Charmeleon/Wartortle/Croconaw/Bayleef/Combusken/Marshtomp/Grovyle/Grotle.
3 - Prinplup/Monferno.
Final stages
1 - Sceptile.
2 - Swampert/Blaziken/Charizard/Venusaur/Blastoise/Feraligatr/Torterra/Empoleon.
3 - Typhlosion.
4 - Infernape.
above 100th place - Meganium.
As you can see, I generally like starters, apart from Chikorita/Meganium, and the Chimchar line (although Chimchar is cool enough).
Still, overall, my favourite starters of each type would be....
(Blaziken is tied with Charizard, but Charizard's sprites aren't that good).
Notice how the fire-type one is the only non-quadraped I like? haha, I'm so sad pointing that out...
