Hey,
Alot of folks here went with G.Skills since (when it came out at the time) it was the best $/performance ratio. I think they still are. Their marketing is very aggressive and they deliver in terms of reliability and performance. I've always been a Corsair guy but since DDR4, i feel like Corsair tried to pull a fast one on me by cranking up their prices and delivering less than stellar cas/frequencies compared to their rivals. In their case, your reaaaallly just pay for the name. Stick with G.skills would be my recommendation.
