I have used them all. Found each own brand to be fab and my DS hasn't had a solid stool since he was 10 months old. Had a batch of Sainburys that had dodgy tabs. The best cheapy make are from Aldi, I think them are called Mamia or something like that, they are superb and much cheaper than the huggies/pampers. They have the Mother and baby silver award for nappies, which is quite something for a packet of cheapies.
I've used shops own on DS, had no problems with them. Also knew a childminder who ended up using the ones Lidl sell on her grandson. They were the best fit.
Tried own brand pull ups and didn't have a great deal of success. Saying that, didn't have a great deal of success with Huggies either, DS has a pampers shaped bottom.
