I think Kharg Island is my favourite on either main mode, although I do play CQ usually. Caspian Border, Seine Border and Operation Firestorm tickle my fancy too.
On a side note, I'm still having "wow moments" in MP, for example when two jets are battling and one dips a little two low, smashing into the landscape as you watch from below. It happened on Caspian Border last night, a jet hit the smaller building right next to (A) at full speed. I was way up the hill capturing (B) and parts of the wreck went hurtling off the rocks and flew past me along the ground, it was epic.
