Reliability being just one factor. A significant benefit of Software RAID 
over hardware RAID is the ability to (for example) yank a disk from one 
Linux box and slap it in any other Linux box (subject to supported 
controller/filsystem).

In the event for example of a RAID1 pair going south, you can take the good 
disk out and put it in another machine, same goes for if the mobo goes pop. 
With hardware RAID you generally need to put the disk in a machine which has 
the same controller (and in many cases) running the same firmware/microcode 
as the original.
