I use Kendall Lille Supreme Maxi. They are the most effective I have tried, but the only others I have tried are cheaper store brands, so I cannot compare them to other high quality brands. Anyway, heres what I thought of them...
The padding is wide and shaped for good coverage.
The plastic backing isn't too noisy and feels good quality.
The wicking and capacity are decent, although I too experienced some leg-cuff leakage while sitting. But while lying down or standing, this hasn't happened.
The tapes stick well, seem strong and have the double layer so they can, in theory, be refastened infinite numbers of times. However, three times has been my maximum before I get my roll of double-sided tape out.
They are not the most discreet nappy I've tried in terms of bulk, although I did choose 'maxi' so no complaints there.
I've slept in them, wet and dry, and found them comfortable. Although I got a rash with the wet one.
The fit has them come up to (or over) the belly button, (and the same height at back, obviously) which is good for coverage, bad for being discreet.
