I think archwing's okay. Like the game as a whole, they do a terrible job at preparing you for it. They assign mission levels to nodes as if they expect you to have a full set of mods collected and leveled as you progress through the planets. To top it off, maxing out your archwing gear does almost nothing to help you in the main game.
You can get other archwings from the Tenno Lab in the dojo. Amesha and Itzal are the two worth grabbing, if you get any of them. Itzal makes looting during archwing easy, and it can move fast, while Amesha pretty much gives you god mode.
If you or anyone else needs help with archwing stuff, I usually won't mind helping if I'm around in game.
