Zelda fairs (pun) alright against samus, and she's like the easiest character to pick up, and play well with in a short amount of time. But the better Samus's will still probably win, and like Ice Climbers, she'll be edge guarded easy as hell. Zelda also doesn't have a reliable vertical KO move, meaning you'll have to rack up the damage or edge guard pretty good to win, so it's still an up hill battle, but if you're losing badly to less than expert Samus with IC's, Zelda might be the way to go, because you won't have to devote alot of time with her. Zelda supposely (according to the Zelda forums, they might be a ltitle biased...) does okay against Peach as well, but I wouldn't know..I don't fight many good Peaches.. She also can pwn Jiggly Puffs. I don't know if IC's got a problem with Jiggly Puff, though.
And I'll defend the thread being in the right forum because it is an analysis of Ice Climbers weaknesses, and which characters make up for them.
