Yeah... I'm among the many Cyndaquil fans...
I can't help it. Cyndaquil is adorable, and I love Fire Pokemon. Charmander's still tops in my book, but Cyndaquil's evolved form is much more adorable than Charmander's (Sorry Charmeleon fans...).

I've tried Chikorita a few times, and it's not bad. I like Chikorita the best out of all the Grass-type starters (in other words, I like it more than Bulbasaur and Treecko). Chikorita has my kind of stats. I'm a defensive trainer.
I mainly don't choose Totodile because Totodile happens to be my sister's favourite of the Johto starters... but I have tried training Totodile, and its physical stats are impressive. I typically prefer Special stats though... which is another reason I don't use Totodile much.
