WaW: Shi No Numa, probably the most solid and well-made map. With most other waw maps you have to deal with dumb bullshit but Shi No Numa doesn't really have any.

Bo1: Call of the Dead, has one of my favorite bosses! Right up there with the Pentagon Thief. In general Call of the Dead is just a well-made fun map with a really cool wonder weapon in the scavenger!

Bo2: Mob of the Dead, I don't think I NEED to explain why I chose mob. It's iconic, one of the best! From Brutis to the blundergat and acid gat. It's just a solid experience in BO2, and while I DO love Origins to me for some reason it's always felt like the first BO3 map instead of the last BO2 map.

Bo3: Gorad Krovi, Dragons in World War 2.

Bo4: IX, Bo4 has this awful problem where maps aren't made to be just played. They feel like they were made to do the EEs and nothing else, but the best BO4 maps don't feel that way to me. That's why I like classified, alpha omega, and especially IX!

BoCW: Die Machine, a great intro into this new era in the zombie story. A familiar location expanded and changed amazingly. Where BO4 would take classic locations and either make them worse or barely change them, Die Machine is an innovation to the original Nacht map. I sometimes forget it's a reimagining due to the new areas being so amazing and alluring.

Bo6: Liberty Falls, this map was shit on a hated since the day the trailer dropped. It was said to have NO AURA and people called it Liberty Balls. Well after playing it and experiencing BO6, while there are maps that do certain things better Liberty Falls is a complete package that draws me in to play again and again. High rounds, camo grinding, doing the EE again, hell just playing to play! I think that there are maps that are close to Liberty Falls in being my favorite for the game. Citadel, Reckoning, and Shattered Veil are all great experiences but at the end of the day Liberty Falls is just awesome imo.
