For the Sinnoh region I did the same thing. But then when I restart every time, I go with Chimchar now. It's a bit more difficult choosing him to start out and I find that very challenging.My first starter was Turtwig in Pearl. I'm glad I picked Turtwig and I don't regret it.
4th Generation and 5th Generation disappoints me as starters. I don't even like the starters of 4th Generation, all 3 of them. 5th Generation I don't mind the Snivy-family but the other two=Disappointed as well
So without further ado, in order:
Favorites:
1- Bulbasaur-Venusaur
2- Torchic-Blaziken
3- Charmander-Charizard
4- Cyndaquil-Typhlosion
5- Totodile-Feraligatr
6- Squirtle-Blastoise
7- Treecko-Sceptile
8- Mudkip-Marshtomp
9- Snivy-Serperior
10- Chikorita-Meganium
The other 5 I didn't list=Don't care for 'em
