My favourite fully evolved starter has to be Torterra. Diamond was my first game, and seeing my cute Turtwig evolve into this fearsome strong beast of a pokemon with a tree growing on it's shell was just amazing. For me, without a doubt, it is one of, if not *the* best designed pokemon. I also love how smaller pokemon live on its back, sometimes for their entire lives.

My favourite unevolved starter pokemon has to be Rowlet (I know its also a grass type starter, but it is just that good). This is the cutest pokemon in existence whilst simultaneously being one of the most terrifying if you just look into it's dead black eyes and wonder what tterrifying things it may have seen.
So, for my favourite water type and fire type starters starters:

Greninja is such a sleek pokemon with one of the best abilities and great moves and stats.

I am not a fan of most of the 1st stage water starters, so I moved onto the second stage. And Wartortle is beautiful with it's gorgeous tail and wing ears. It really is a pity Blastoise lost these defining features.

I know that Charizard may be a bit overused (a lot more than the average Kanto pokemon) but I don't mind it too much when it has such a good design. The X and Y megas only made it better, with one finally giving it the dragon typing it deserved and the other making it even better with the typing it had (although I think the X mega was more than enough).

It just has a lot of personality. Not much to say here.
