I mean, it is better.
In training server, you have people taking off into each other, people landing on grass or at 250 knots, and some unprofessional ATC or even trollers.
Plus, all the traffic goes to KLAX and EGLL usually.
In expert server, there is a dedicated schedule and although traffic goes to airports in a specific region (each day), at least you don’t see KLAX and EGLL being controlled every day and getting all the traffic. Plus, the ATC on ES are trained 😉
