United recorded only their second win in five games by beating local Hong Kong outfit Kitchee FC 5-2.
It was a satisfactory end to a long trip.
But for Moyes, who only officially took charge on July 1, it was an invaluable experience.
"I am taking away the great experience of my first trip with Manchester United in general and what the football club means around the world," he said.
"I have also had a chance to get to know the players and try to settle into my new environment and for the players to get to know me as well.
"They have been working with a great manager for a long time a lot of them, so it is going to take time.
"But I have really enjoyed working with them. They have been incredibly professional.
"I can see why they are champions because of the way they conduct themselves and go about their business.
"I have been very impressed."
Due to land on Tuesday morning after heading straight to the airport following the final whistle, Moyes will be reunited with Wayne Rooney, who is scheduled to play in Sweden next Tuesday.
He may also decide whether to turn interest in Marouane Fellaini and Leighton Baines into a formal offer.
In Fellaini's case the matter is complicated by a clause, thought to be set at £22million, which is due to expire on Wednesday.
Moyes' conundrum is whether to activate the clause by offering the stated amount, or allow it to lapse in the belief he could get the Belgian for a lower figure given, apparently, he is surplus to requirements at Goodison Park.
