In my experience, yes, it's definitely true. I suspect it's more a
matter of tolerating small misalignments better than a matter of
better S/N ratio.
I also reserve a couple of drives for "tough cases". Not all 360K
drives perform the same when recovering marginal media and I reserve
the very good drives for special occasions.
One thing that few people realize is that not all drives are equally
competent when it comes to clamping media "dead center". Almost all
(I have some very old drives that don't) spin the motor as the disk
is being clamped by the hub mechanism, but some do the clamping job
better.
