Honestly, I don't care for them. I think LEDs look tacky and the power supply is not that efficient.
The Corsair CX is generally very reliable, and more efficient than the GS series. It can be found for cheaper and is a great choice for builds on a budget.
If you are looking for a more premium choice, the Corsair RM and AX series are great choices.
Seasonic and EVGA more great power supplies as well.
