In flight : good to very good even domestic flights.
BUT :

- Lounges at SVO are a pain, worst than the worst *A lounge. I don't mention the behavior of rude locals when it comes to "free stuffs"... food selection is average to poor, beverage selection is very poor, you have to fight or wait to get a seat, noisy, smelly, overcrowded.

- Fast track : a big joke. Long queues and no fast strack for domestic (messy security area).

- Boarding : big mess again because locals does not respect any rules and rush to boarding counter. So no real priority boarding and be ready for again a big mess at boarding.

Only think i love at MOW airports : the express train. Amazing and fast.
