we use huggies and woollies select.
I only get the huggies when they are on sale, so for us they are good value as they rarely leak (and only when our heavy wetting DS splits them!).

woollies select I would have voted for until this week, when more than half of the nappies from the box I bought recently have had the grip tabs break wither when I put them on, or while he's been wearing them, so I've only noticed when I've changed him.
