I just bought some Snugglers too (they sucked everybody in with that special didn't they ). They don't give ds nappy rash- the Woolies Select, Coles, BabyLove all do. But they did leak, and we had one unfortunate poo incident with them too I think the only real difference is they don't have the elastic bit across the back. But that little piece of elastic seems to make a huge difference to there effectiveness.
I have a couple of friends who swear by Aldi but I haven't tried them yet. I think I'm going to stick with Huggies- cheaper to just buy them than waste money on packets of different brands that I can't use and have to buy Huggies anyway!
