The newer one is MLC, which I would not trust.

I killed 2 MLC sandisk 8GB cards by doing Ubuntu installs, then adding lots of packages and then using the machines heavily for about 3 weeks. I mounted /tmp and /var/tmp in ram and mounted /usr, where most of my files were as read only. The first time, I took the laptop to a conference to use it as my main machine. I was surprised it died so quickly. I wanted to find out if it was a fluke, so I used another card and tried it again when I got home. After a month, that card died, too. That was enough to convince me. If MLC works for you, that is great. I think I did a fair enough test that I won't trust it and advise against it. With that said, for a camera, I think MLC is generally fine. It is hard to take enough pictures for it to be a problem. In the right scenario, computers can be OK, but I would rather have the extra life of SLC. It is a full order of magnitude more durable.
