I like all the starters
Rowlet is my main, no question. Been hoping for a grass owl since those Cactowl B2/W2 fakes. Your spirit will live on through Rowlet my brave Cactowl ^-^
Litten is adorable and the guy I'm dating will absolutely love this thing
Popplio I can see being the underdog starter this gen already. I think it's the somewhat derpy face that's offputting but I bet this thing will probably have the coolest final form ironically.
The only thing a little disappointing to me is the region itself. We just came from an island/tropic region in the Hoenn remakes so I was hoping for a drastically different region this time, somewhere snowy and remote preferably. Guess it'll have to wait to next gen. I do REALLY like what I'm assuming to be the rival's design, very unique compared to past rivals.
Over all, I'm very happy. Can't wait to see more Pokemon over the coming months in Corocoro leaks.
