Great question Obio. Some must-haves in my opinion:
Arromanches (50's era French Carrier)
Ark Royal (circa 1960's)
Clawson's WWII CV-2 World Cruise (it'll take you weeks to fly from each location, there's so many locations - bravo Paul!!!)
Yanco's Midway USN/IJN Carriers (amazing WWII Carriers)
Alphasim CVN-65 Enterprise
All save the latter is freeware. There's a freeware version of it (one location only, in PR) at flightsim.com
I use RCBCO for traps - I really like the sound cues at trap, which I don't believe come with 3Wire. You need to set locations and gauges - but most of the locations have been mapped for most carriers out there, and gauges only takes a few minutes to set into your panel (depending on how fussy you are - I am very picky, and kinda slow, but I can put the gauges into any panel in around 15 min).
enjoy!
