I have to say I wish I could get a little of that shine. It always dries
some what mat (though not paper surface mat) and after the gum coats are
developed and dried, that seems to negate the shinney/glossy surface
appearance issues though frankly I've never done a side by side comparison.

I am a Gamblin PVA user (1:2) but I do want to point out that there is a
shiny factor (i.e. not matte) associated with it which some traditional
gummists take issue.
