Okay the TactX Keyboard is actually the same price as the G15 in some stores so @AD Alienware's Keyboard is not overpriced. Now in some stores Alienware will be cheaper and for others more expensive opposed to G15 so shop around and google each under shopping search results. Now as far as which is better I would say the TactX Keyboard since it was released recently but the G15 does have a lot of added features. So it really goes by your personality. Both have good key responses and are solid. I believe the G15 also has G keys which can be customized for certain movements and actions just like the TactX.
