Mist nest hell drops something which ggn/vn hell does not?

[Twaha]

Because it costs 400 gold and 3 additional entry ticket token does it give more of the unique or legend mats?

Harmony Cube?

Other than that, I'm pretty sure the loot is similar to VN Hell/GGN Hell x3.

Aside from harmony cubes nothing new there. People just do it because it's 'faster'
