K, my favorite Type is Ice, my fourth favorite Type is Electric, and one of my least favorite Types is Fire. So, in order of preference:
Moltres
Zapdos
Articuno
Surprised? Well, honestly, I passionately dislike Articuno. This thing gives Charizard a run for its money in overratedness. Except, amazingly, Charizard's actually more useful than this flying failure ._. Charizard, while annoyingly difficult to use, can work well in the right circumstances. Whatever you're trying to do with Articuno, it won't work. Fact of the matter, Articuno has far too many weaknesses and far too small a movepool to be effective.
The aesthetic appeal is, if anything, even more pathetic. Anything with a long billowing tail is instantly beautiful, eh? =/ How sad. Lol, who needs originality when you can just ogle a long blue tail? 8D
Zapdos is easily the most useful of them, and it's a good Pokémon. But I'm not really that fond of it, for some reason.
Moltres is my favorite of the three, oddly. There's just something about the thing that draws me in >>;; I do have a darn strong Moltres, but I know I liked it before that. Meh xD
