Depends on which scopes you like the most. The phantom have the 3.4-4x scopes and 1-2x reflex sights. IMO these are horrible as the phantom, like the Ghost, have the sniper rifle sway. The Phantom does however do more damage than the Nyx, but cannot get the laser attachment thus making the Nyx a viable CQC weapon. Nyx though, like the Artemis, does not have any sway which makes it a very potent scout rifle. It isn't a brutish weapon but rather a surgical tool. So I favour the Nyx with the 6x scope, 7x wasn't quite close enough but 6x works beautifully. Indeed, it makes you feel like an assassin. You can also scope fire without too much effort due to the lack of sway and that the 6x zoom makes quite a lot of difference from 7x. If the Ghost had shared these qualities I'd be all over that as well but contrary to what some say it DOES have sway, and like the Phantom it has pretty terrible scopes available to it. Ghost and Phantom are classed as sniper rifles, just so people don't get them confused with scout rifles.
