What's the deal with glitter eyeliners

I admit that i'm not the biggest fan of glitter liners but they are undoubtably popular so I felt that a little investigation might be needed to determine the good from the not so.
It seems that some of the cheaper drugstore brands have got this dialled.

The Collection 2000 Glam Crystals liners are jam packed with glitter particles suspended in coloured gel which often eliminates the need to use another liner before hand. 14 shades available.

The new MUA range from Superdrug features 10 shades of glitter liner.
Every single item in this range is £1.00. I tried Shade 2 which is a beautiful true gold, not yellow, pink or green. The glitter is set in a clear gel but there is so much glitter in this product that it does not look patchy or sparse, possibly helped by the brush which is excellent. A ridiculous bargain for a pound.

Urban Decay Heavy Metal liners have the finest grade of glitter. They certainly have the most sparkle but they need to be layered over another opaque liner to get the full effect as they can appear patchy and reapplication often lifts off the glitter already placed.

I have tried 2 of the Models Own glitters. I liked neither. The gel was too watery and the glitter too fine and sparse.

Note: Another brand to check for good glitter liners is Sleek Make-up.
