Need help and advice on mixed consoles,pcs

Has anyone had success getting a big party together with multiple inputs? That sounds dirty. Lol
Should we bother, or wait till 343 comes back a bit from holiday?
I keep seeing posts about desync, btb being down, etc.
I dont wanna put the OGs through another MCC launch if it could be helped.
