I think it depends entirely on what you're looking for in a palette--it's not even a matter of quality vs. quantity, it's just a matter of what you'd actually use. Personally, I use N2 and the Pro palette daily but I almost never use my original Naked palette anymore.
In terms of quality, I think they're essentially on-par; just as easy to blend, not chalky, and just as pigmented. L: Lorac "gold" vs. UD "half baked" (w/flash); R: PRO "taupe" vs. N1 "buck" vs. N2 "tease" (no flash):
Naked I: palette itself has a magnetic flap and a tiny mirror. 12 shadows, only two of which are matte (nude and slightly darker nude). A lot of shadows aren't even shimmery, they're straight-up glittery. It doesn't even have a matte brow highlighter, or even a matte dark shadow. comes with a single-sided brush.
Naked II:
huge improvement on the palette design--sturdy metal snap box, huge mirror, great for travel. 3 matte shadows: a cream brow highlighter, nude brown, and black (I think these three are essential to have if you don't already). The shimmery shadows, though, are a
lot more wearable than N1--only "creep" has that typical UD chunky/sparse glitter, the rest are subtly shimmery. comes with a double-sided brush.
Lorac Pro: this palette is super slim; like N1, only has a magnetic flap. 7 shadows are matte, 9 are shimmery. In general, many of the shades are pinker in tone than their UD counterparts (cream, lt pink, mauve, garnet, etc). "nude', "champagne", and "lt bronze" seem a tad bit redundant, but other than that all the colors are very different. Be warned: when Lorac does shimmery, they mean REALLY shimmery. Here's N2's "busted" to Pro's "garnet" (flash on):
Because the Pro palette's shimmery shadows are SUPER shimmery, I'd say N2 shimmery shadows are more wearable/versatile. But in general, because of how many eyeshadows it contains--and how each shadow is different from the other--I'd say the Lorac PRO palette is more versatile, and a better bargain. Has every shadow you'd really need: matte black, dark brown, nude brown, shimmery shadows, brow highlighter, etc. Comes with travel tube of eyeshadow primer.
In sum: N2 is more wearable (to me) and the palette itself is sturdier; PRO is more versatile (though still very wearable) and more bang for your buck. Hope that helps!
