Well first off, my notebook is mission critical when I'm traveling for work.. so I value reliability and compatibility first. Performance is important too, but the move to SSD is so huge. To me it's almost splitting hairs beyond that.
I favor the Intel drives for these reasons. The G2 drives have been rock solid, and the 320's are looking good as well. I think they're a good bet since they use the same controller, but of course with different firmware. The Intel drives also make it easy to perform firmware updates on Macs, unlike the Sandforce units. The Intel G2 drives have lead the pack with low failure rates, and Anand had some encouraging things to say about Intel's belief that the 320's even improve this further.
So I guess 100% proven, Intel G2. Less proven, but looking good so far, Intel 320. If you don't mind -possible- hibernation problems, plus clumsy firmware upgrades then you can consider the OWC drives.
The Intel 510 looks promising too, but only for a SATA II controller at this time. It's not rock solid with the new 2011 MBPs. Lots of potential for the new Sandforce drives as well as the new Crucial.. but time will tell.
