Hi, I use totsbots cloth nappies on my 4 month old and they are fabulous. I've not used the two brands you have, but tots bots only fit from about 9lb, though could be a bit more or less depending on the baby's shape. Mine is skinny so was about 9 and a half before they'd fit her.
Personally I disagree with the commonly held belief that cloth means more washing as in my experience they hold everything much better so though I am washing nappies, I am washing less clothes and bedding as a result of no longer having to deal with the explosions we had with the disposables. It's much the same either way. My nappies also dry impressively quickly - about 3 hours in the airing cupboard does the trick. It really isn't the chore it once was. Very little difference from using disposables as far as work goes.
We used disposables briefly when my daughter was first born as she was 6lb8 and skinny so our cloth nappies didn't fit. We tried and failed with sainsburys as the fit was wrong. Pampers fitted better, but still tended to shoot poo up out the back - a problem I've not yet encountered with cloth. Be prepared to try a few to see what you and your baby get on with as the size and shape of babies vary greatly and different sorts suit different kids. We got given some Aldi ones (no Aldi near us) and they worked pretty well. As good as pampers tbh.
Good luck in whatever you decide.
