I've tried a couple of micellar waters, and the Garnier one suits me - it's light and soothing, and does seem to clean off all the gunk. I also tried Superdrug's own cheapo, which seems pretty good. I suppose 'yer pays yer money and yer takes yer choice'
Like you, Nanasam, I hate thick, gloopy creams, so micellar waters have been a bit of a blessing for me. I was afraid that they would disagree with my very dry, sensitive skin, but if anything they are more calming than creams.
I suppose a good idea is to start with a budget one, and work upwards until you find the one that suits you. I'm a bit of a tightwad, so if I can find a good 'own-brand' I would go for that every time!
