Both are fantastic, whichever you like the look of.
EVGA are probably the best brand around for GPUs, fantastic customer service, they go out of their way and put any issue behind the company, and will not charge you for shipping.
Support and long warranty combined with high build quality make them probably the best around.
Here's an alternative if you really don't want the SC though, I recommend the Amp Extreme or FTW.

There's a strix card, but it performs terribly for the money and is mediocre compared to the top end cards that can be bought for LESS.
