For me, ide-tape was easier to set up for all IDE systems (typical low end).
I had to stop using it with kernel-2.4.20 because it simply doesn't
work at all anymore (crashes system).  Setting up for ide-scsi tape
adds several more steps to an install (including append="hdd=ide-scsi" for the
boot loader).

Furthermore, the ide-scsi+st driver prints all kinds of errors on the console
about commands not being recognized when using a low end IDE tape, but the tape
works fine.  Not having looked at the guts of the code, I suspect that ide-tape
knows more about which commands low end IDE drives don't support.

So there is a lot of overlap between ide-scsi+st and ide-tape, but ide-tape
specializes in low end drives - and doesn't expect full SCSI tape compliance.
