The map design for Bangkok is awful in contracts mode and the main mission isn’t really interesting either.Jordan Cross has a really interesting personality and some really cool kill methods but the bad map design really ruins his route.Ken Morgan has a decent route and there are some good ways to isolate him,but his kill methods are pretty boring and he lacks in personality.
About Marrakesh:well,I think Marrakesh is a bit underrated and if you aksed me,I think I would even say Marrakesh is just as good as Paris.This is the only mission in Africa in the franchise,so its atmosphere is truly unique.There are some really cool kill methods for both targets(double fire/APC turret kill,falling moose,falling toilet,printer kill,neck snap during massage/prisoner interrogation) and the story is pretty interesting too.The two fortresses aren’t really well designed in terms of entrances and exits but I like their uniqueness in terms of infiltration(the school is a hostile area full of soldiers,while in the consulate the only NPCs who can spot you tresspassing are the guards and the janitors-not even the target himself minds seeing you in the consulate in your suit. 
).It is also cool how you can use the tunnel opportunity to bring the targets closer to each other in my opinion.
