You should also play Beyond the Red Line's demo and The Babylon Project.
I don't know about BtRL, but TBP isn't a campaign as such (though it does include the Earth-Minbari-War mini-campaign), but there are quite a few campaigns out for it.
If you really want a top 10, I suggest you gather all the campaign names given in this thread together and start a new thread with a vote to see which campaigns are the most liked.
Mine would be without any particular order among themselfs:
VA:
Blue Planet: AoA, Derelict,
Dark Children, FreeSpace Port,
Raider Wars, Silent Thread Reborn
non-VA:
BluePlanet: WiH,
Earth-Brakiri-War,
Fortune Hunters, Sol: A History, Uncharted Terretory, Warzones (despite an overabundance of "white-out" suns

), Wings of Dawn
Ittalic entries are for The Babylon Project
Va for Fortune Hunters is currently being worked on and there was also an effort to get Uncharted Terretory VAed, but I don't know wether this one is still going.
Vassagos Dirge.... the missions are nice, but the setting and especially the music (some very slow classical music just doesn't fit into a fast paces dogfight) really ruin the mood for me, hence it didn't make it into my list.
Homesick was also a lot of fun, but I don't remember it well enough to decide wether it should be in the list.... I gotta replay that again.
