Both are fast flash memory types it's just that the manufactures have approached their advertising in diferant ways.
Sandisk is obviously the bigger brand but flash memory on the whole is pretty reliable.
As for actual speed in use, there is a differance between standard and high speed memory types but I doubt you would notice it between these two being of similar spec.
I can say take these performance figures with a pinch of salt, they are purely theoretical max's, in every day use transfer speeds don't come anywhere close to these figures.
When I use my 40x CF 512 Fuji's on a USB2 card reader (480Mbits/sec 60mb/sec) it takes up to 4 minutes to transfer a whole cards worth of pictures to the hard drive.
The most important benefit of fast flash types is fast writes, this enables multiple frames to be taken in quick succession for sports or action photography.
Taking a little longer to download the pictures is no hardship.
