Well if they don't show the final evolution for the starters I might go with Froakie.. The most favourite grass I like though is Jumpluff. At one point it was my favourite Pokemon ever but Masquerain took over.
Vivillon is cutesy butterfly though its alright. I prefer Beautifly design wise. I choose my Pokemon based on their appearance rather than stats or how strong/powerful they are..
I love grass type too! My faves are Jumpluff, Whimsicott, Vileplume, Cherrim, Leafeon, Serperior, Roselia and Celebi..
I don't like Fennekin as bipedal. Even though its quite good. I was expecting it to be quadruped but whatever..
I might end up changing them too. I used to like Pancham but I didn't like Pangoro.. I used to like Fletchling but not so much ATM.. I'm still considering Vivillon as I always catch an early bug on my first run through.
I prefer the majestic Xerneas than the ferocious Yveltal.
I've noticed you are choosing Grass pokes! Well for me I was really bummed that Fennekin's second stage is bipedal so I am not choosing it anymore. I think I might end up choosing Frokie.. I'm going to judge Chespin in its final evo.. Right now I have no definite choice..
I'm seriously going to get Skrelp, Male Nyaonikusu and Amarusu the fossil Rock/Ice Dino..
