audio engine's will be nice if you want accuracy in your music, thought the downside is you dont get an amp with it so it wont neccessarily be able to represent the lows well enough.
The corsairs come with a sub, and while they are not studio monitors and more tuned towards sound effects and booms and clicks of modern games, they are surprisingly nice to listen to.
I feel like the Corsairs are more versatile, but honestly if i were you, id get the audioengine's, and shell out another 150 or so for the Fostex SubMINI. then you'll have a audiophile set up while still being able to game on it.
tldr:
the corsairs are better for bang vs buck, but if youre gonna go with studio monitors i'd at least get a sub too.
