for me kings row, junkertown and dorado are far above everything else in the game(just my opinion) and pretty much any 2cp can go on worst maps but paris, horizon and watchpoint/havana(usually i enjoy escort but wow) are worst for me Eichenwalde and hollywood are not bad maps
Top 3:
Havana
Kingsrow
Junkertown
Bottom 3:
Horizon
Paris
Illios Well (the other 2 are alright)
Top 3:

Top 3:
Lijang tower
Nepal
Oasis
Bottom 3:
HLC
Paris
Anubis
Basically KOTH is by far the most functional game mode in OW, and those 3 are the least snipe-y. 2cp is bad and those three are the worst.
