I’ve never flown Emirates but from what I’ve heard and read, the service is almost impeccable - even if you’re sitting in coach.
I have flown a few times from Dubai to Chennai, and yes they have great service, friendly efficient and smokin hawt!!
I’ve flown Emirates several times non-stop from the UAE back to the States. They treat everyone well. No complaints - I’d fly them anytime.
I’ve flown both First and Economy on Emirates. The service is impeccable in First and the service is as good as it can realistically be in Economy.
