Lexar ranks right up there with Sandisk, and may be a little less expensive.
I lost some memorable images on Lexar. Will never use them again. Never happened with Sandisk. You will no doubt say I am biased. And you would be correct.
Sandisk is great - I have 2 of their fast Extreme cards, BUT when I bought my Sony A77II some fellow hogs that owned the same camera said that PNY had a card that performed better than the Sandisk in that camera. I bought a PNY card directly from PNY (they are in New Jersey) and paid half of what the Sandisk cost me. In terms of performance, I frankly can't tell the difference - they are both great cards.
