The short answer:

MIS glossy-compatible inks use a gloss optimizer as the base to stick them
on the paper.  The Epson and HP pigments use a coating on the particle to
stick them down.  The visual difference is, as you've noted, the coated
pigments are glossier.

My longer personal comments:

The MIS gloss optimizer approach also has significant advantages.  The glop
base holds reflective artifacts to a minimum.  See the HP PK plus MIS Gloss
Optimizer (HpGO) I have installed in the 1100:

(This may be the best neutral glossy inkset approach I know about for fine
art.  Because it uses MIS R800 Gloss Optimizer as the base and MIS PK, the
components are all available at very competitive prices.  I think HP Z3100
PK pigments have proved themselves to be fine art quality in
Aardengurg-Imaging tests.  See http://www.aardenburg-imaging.com/   It's
easy to mix (pour bottles together 2:1 to make an LK density ink).  The 1100
beta has yet to have a single bad nozzle check.  It's my default office
printer left on 24/7.   HpGO will be half of a "Dual Quad" setup on the 7800
next.)

The bottom line for me has been that the MIS approach does very well for
wall display, and the coated approach shines at higher gloss.  The higher
gloss approaches win for cards and snapshots.

If you want super high gloss without the reflective artifacts of the coated
OEM pigments, the Claria & Epson-Noritsu advanced dyes make all the pigments
look bad, in my opinion.
See http://www.paulroark.com/BW-Info/BW-Dye.pdf

So, I've been using a dye PK (Claria or Noritsu [by Epson] and user-diluted
LK in a 1400 for cards.

It's easy to use QTR to print a black only Claria image on Red River
Metallic paper to see the look that has been fun for me lately.  See
