Keep in mind what you get from chests is random and isn't always a special item. It will take you many tries to get everything.
8bit link gives the OG LoZ tunic (3 pieces hat, shirt and pants) as well as the sword and 8bit paraglider. OoT Link gives the OoT outfit (3 pieces) and big goron's sword. There's probably a paraglider too but I don't have it yet. Majora's Mask gives the fierce deity outfit (like the others 3 pieces) and the fierce deity sword and there's a Majora's Mask paraglider material that looks cool. Twilight Princess amiibo always gives Epona on first scan who you can register at a stable. After that there's the twilight princess armor. I assume there's a paraglider too. Don't think TP link has a unique weapon. Wind Waker has the wind waker outfit, sea breeze boomerang and probably a para-glider. Skyward Sword has the outfit, goddess sword and Fi themed glider. Link's Awakening has the Link's Awakening outfit (which makes him look silly). Zelda's Smash Bros amiibo can drop the "Dusk Bow" which is a good bow which shoots long range arrows, but it's way worse than in OG BoTW when it was the Bow of Light which shot infinite light arrows that basically never lost height. Toon Zelda can drop the Wind Waker shield which is almost as good as the Hylian Shield. Ganondorf Smah Bros amiibo can drop the sages sealing sword from TP. Shiek can drop Shiek's mask. Midna and Wolf Link sadly no longer gives you a wolf link companion like it used to. Now it just gives you a bunch of meat. That's all I can think of off the top of my head.
