Express is the only one that I don't really enjoy. Carrier is fine for FFA and Party Games, Aftermath is ok in Ground War, Plaza is a laugh in Dom/Demo etc, but I can't find one mode where Express is fun.
Hijacked and slums. Whilst having linear maps isnt always a bad thing having 2 maps where the team who maintain their positions at the 2/3 of the map mark able to completely dominate is ridiculous. Teams annihilate and if you play solo you get ****** over because teammates rush and reset the spawns every 30 seconds... so unless you are in tune with said rushing teammate you will end up being shot in the back.
Slums - 2 people guard the house, 2 people watch the centre opening into the fountain yard and 2 people watch the other opening on the side opposite the house by hiding behind the obvious cover. Impossible to beat.
Hijacked - (pick either top or bottom of map doesnt matter) 4 guys watching the right and left sides of the boat, 1 watching the door to the inside area and 1 guy hides in the underground. You cant lose if you get this going.
Every map has the ability to be controlled but its far 2 easy on these ones.
