So I'm in a spot where I need a single legendary for two different decks and I'm wondering which one to craft. The first one is Aluneth for a secret/tempo mage, and the other one is Kathrena Winterwisp for a big beast hunter type of deck (https://www.hearthpwn.com/decks/1038913-fifth-best-deck-on-ladder-i-will-hunt-you-down something like this). What are your experiences with those decks, and what is the better choice overall?

Though Aluneth is probably the better option, secret mage is losing a couple of good cards with the new rotation coming up (Medivh's Valet, Kabal Crystal Runner , Firelands Portal ) are just examples. That being said, those cards will probably just be replaced with new ones that keep the archetype alive. 

Right now is a super awkward time to be crafting legendaries. I have played against a couple of Kathrena Winterwisp decks, and though my opponent seems to pull off that combo every time with King Krush, I feel like that deck would get boring quickly.

Yeah the rotation is something i've taken into consideration, also i've already got 2 Mage decks (Big and Exodia) and none for Hunter after the nerfs (I also need only Rhok'delar for a spell hunter). It's awkward for sure.

Unless your swimming in dust, save it. In April the meta will be drastically different after the rotation. There is no way to tell what will be great or garbage after that happens.

Aluneth is absolute wank. No I mean it, stupid overdraw card and is highly ineffective imho. And most other people's opinions. 

Do you have Malygos? If not, make him instead - much more fun card. 

I've always wanted him, but i don't see how he's going to be useful in this meta

Malygos , Twig of the World Tree , Ixlid, Fungal Lord , Faceless Manipulator

Jungle Giants quest combo. Super easy to pull off, but expensive deck.

Just play ixlid, manipulator it, then play malygos. That combo fills your board with 3 Ixlids and 4 Malygos. 21 damage Moonfire and also 24 damage Swipe
