I have to admit that having been matched gold by Malev I used BUD more this year... but having BUD as destination!
The transit do not look very attractive and lounges are a bit basic like those of LOT (but worse than CSA).

The BUD airport is under renovation but they MUST seriously improve the security lanes for people checking-in BUD. With Gold I have max 10 mn wait but on Sunday evening as normal passenger you can wait 45minutes and that's really horrible and creating irritation and chaos.
I also add that the stupid system with automatic trays is really unuseful and unfriendly as it creates more chaos than anything else.
I think they got it because the airport is partially owned by Germans and the company that invented that system is German...
That system works only in CPH and few other places where they have billions to waste on it buying many lanes... but the old manual way is still the BEST one and go faster!
