Fact: When you add a lot of opaque non-sparkly pigments in a formula to make it opaque, they can "muddy"-up and dull the shine of the sparkle pigments. Kinda like dropping glitter in cloudy water. So for the sparkle to shine through, brands often have to keep the base translucent, or else throw in SO much sparkly mica that the product can feel slightly gritty and sometimes harder to work with. Hence, in most "intense" gloss ranges, the sparkly glosses will always be slightly translucent.
I can't tell you what shades are my fave. It's too hard to pick because these are actually all gorgeous. I would say since this is a high-color gloss range, don't play it safe and keep buying the nudes and soft pinks. (You can get those shades from any drugstore brand.) Try a bright magenta pink like Scandal, a rich red like Brickhouse, one of the beautifully sparkly sheer shades like Big Bang and Vice, or even step out of your comfort zone and try Bittersweet, a bright grape-candy purple which is the campaign color for the range, which is actually incredibly flattering.
