Chikorita is really that hard to play with?

I'm currently playing through Crystal after beating Heart Gold and Gold a time ago. I want to complete the Pokedex and so.

Well, I don't like Feraligatr's design and chose Typhlosion twice already so I decided to choose Chikorita for the first time ever. I'm in Ecruteak and so far it didn't give me any trouble.

Is it really THAT hard to play with Chikorita's line here on?
