In your list i would go with the Intel X25 due to thorough testing and reliability of that drive.
IMO I think you should consider the OCZ vertex 2 as it offers better performance which does not degrade over time like the intel SSD.
The problem with Sandforce based drives is their inability to HIBERNATE (where data is saved to the hard drive) rather than SLEEP (where data is saved to RAM).
I believe the sleep function is operational on all sandforce based rives.
For peace of mind and if you are willing to accept slower performance (which is noticeable) then stick with the X25
