I got LSTB before RRS but also I was expecting LSTB to be less vibrant than ATU, actually liked that more muted, less contrasty quality and the fact that the base colour was more opaque. Whereas I'd seen swatches of RRS that were just exploding with the big hex glitter jumping out of the black jelly, and it was specifically that big hex effect I was looking for over and above the smaller glitter.
As for colour on wheels, I think I put together wheels with outfits in mind - I don't mean I match outfits to nails, but I'd want to avoid clashing tones. Although knowing my colour family and trying to make sure new purchases are all within a certain tonal range should mean that I have fewer opportunities to clash. I only have one wheel that refers to finish rather than colour and that's the one for flakies and transparent glitters, to be superimposed on other colours mainly.
Here are pics - my nail wheel swatches aren't too bad, this was I think 3 thinly applied coats, a great improvement on my "slap it on to get more hex" attempt, anyway. The last wheel pic, with flash, I've not embedded just attached as it's HUGE: click then click again for full size.
