Articuno > Moltres > Zapdos.
But they're all great.
back to being a non-edible pastry
easy choice, Articuno i always liked him more then the other 2.
second comes Zapdos.
I love Kanto birds, designwise, they are my favorite legendaries.
Articuno gets my vote here, because he's my second favorite Pokemon. I love Ice types, and in my opinion, Articuno has the best design in all Pokemon, and he's very useful.
Zapdos is still one of the best Electric types in the game, I used Zapdos so many times in different games. It's a really close second after Articuno for me.
Moltres is my least favorite of these three, but i like him too. It comes last mostly because of, I'm not the biggest fan of Fire types.
The majestic, elegant, and absolutely dazzling blue bird Articuno has been one of my favourite legendaries since Gen 1. Articuno has hidden possibilities in competitive battle that not many have explored.
Apart from it's terrible Rock weakness it is quite a defensive Pokemon and can be a dark horse in battle to those that are not prepared. It's not the most expected Pokemon in a battle now, which gives it a slight edge.
I find Articuno more appealing then Zapdos and Moltres, too bad it's the worst of the three (If only it learned a Ground type move).
Ground type moves won't fix its biggest weakness: Stealth Rock.

Articuno's my least favourite of the three. I never really liked it, but Moltres and Zapdos are both cool. Zapdos would be my favourite, love that bird.
Starters of choice.

I would say that Zapdos is my favorite of the three, mostly because I love that one of the second movie.
Plus, between Ice, Electric and Fire, my favorite type is Electric.
As usual, I couldn't care less about which one is better in a battle.
