What's so great about gel eyeliners?

Just some rambling today, no picture, I think, at least at this point in time I don't think I'll put any picture in this post.

You hear about how people keep going on and on about how great gel eyeliner such as MAC Fluidline and Bobbi Brown Long Wear Gel Liner are, but what some don't realise is that gel liners may not be suitable for every look.

1. Using gel liners to line your eyes will definitely make your eyes look more defined. However, does it suit the look you're going for? For example, if you're going for the Japanese shimmery makeup look, the gel liner may look too harsh compared to the 'soft' look of the shimmery eye colour.

2. It takes helluva lot of practice before you can actually draw nice clean lines with your gel liner, using whatever size brush you're using. MAC has this flat liner brush, which I don't think is all that great. I prefer using the line brush with really fine tip, almost as if there are like 10 strands of hair or less on the brush.

3. It is easier to blend pencil liner than it is to blend gel liner. When attempting to 'blend' the gel liner with shadow, the gel liner kinda flakes. I don't know, maybe the gel liners are not made to be 'blended' to anything else.

4. Gel liner produce very defined lines suitable for cat eyes, smokey eyes and generally any makeup you'll put on at night. For day time, it'll be safer to stick to pencil eyeliner.

5. Generally speaking, gel eyeliner stay on much longer than pencil eyeliner, oily lids or not. But there are ways to make the pencil liner stay just as long.

So, what do you think?

p/s:- for some reason this week I seem to think that I'm fair and have been mixing foundations and concealers to be too fair. Pics turn out like shit in the end with white stuff at my eyebag area. Urg. Time to stop wishing I was fair.

*EDIT*
Flaking of gel liners were due to my BB gel liner being slightly dried out :(
