The syntax and matching rules of an attribute need to be chosen
carefully based upon the intended use in applications of the
attribute type.  Having zero clue as to how you intend to use
this attribute type, I frankly cannot not make a recommendation
on which syntax and matching rules are most appropriate.

I would say it matters more to design the schema to meet the
application needs then to worry about what are minor influences
to the performance of the directory server.
