I would avoid KLAX, EGLL and KJFK. My only bad ATC experience was at KLAX. Try places like RJTT, VHHH, WSSS, pilots follow your instructions 98% of the time. You’ll probably get less landings but quality experience.
But sometimes I fly on TS and I have to say I am guilty of ignoring ATC commands because ATC is either trolling or giving wrong instructions, which also kills the realism and fun. Could be the case for other pilots so TS can be a mess.
I’d choose other airports and not rush through the landings, enjoy them:)
