I really think I do not have much of a problem telling things apart.  I
think it takes a trained eye and a few years in the field helps.  What I
find interesting is some of us do not see what others see.  I once tried
to explain the differences between the various members of the Scaphella
genus to another collector and spent 15 minutes trying to do it.  I
realized later that this person would never see what I do.  Our views
were profoundly different.  What can be more difficult is the lumping
and splitting part of it which is the next step.  In the case of
Scaphellas I tend to stay away from that but I do have my own opinions.

To make things worse, I suspect there is chaos below the species level.
There might be shells that are neither full species or subspecies but
are actually somewhere inbetween these two levels.
