I've gone for an F-4 - Good at most roles, easily capable of being upgraded to carry more modern weapons, and can be used both on a carrier and on land. I also picked it because I had the idea of playing a Marine Corps pilot, and it was an aircraft the USMC used, which means it fits in with the idea for the AC setting as well. 

I was tempted by the F-5 or the Skyhawk, but I've used those in other RP's, and wanted to get my hands on a 'toom for a while. 
That's all assuming Rafale is okay for me to join in the first place though >.< 

The Mirage is a good choice either way - it's fast, agile, looks nice and has a good complement of multi-role munitions. And again, if you decide to/get the choice to stick with Mirage variants, there's plenty of other more modern ones to look toward.

EDIT: By the way, your signature is hypnotic, and hilarious xD
