Route 66 and Dorado. Tbh I just hate most escort maps because I seem to always be put in teams with dumbasses who don't seem to understand that when you're on an escort map, on def you need to actually get close enough to the payload to contest it and stop it moving, because otherwise the enemy team will just win, and that when you're on attack you need to actually stay by the payload to keep it moving.
If I'm excluding escort maps, I'm not a massive fan of Hanamura with the second point. As 2CP maps go it's probably the hardest to def but at the same time it's not massively easy to attack if you have a team who doesn't take advantage of the side routes
