I started using as planning to get for Dd so thought I should road test.
I have some Modibodi, which are about £20 each and some cheeky wipes which I think about £8 each.
Modibodi are much better imo, really reliable, I'd think they would last a whole school day, cheeky wipes just for light flow.
Modibodi ones material feels more like a bikini, cheeky wipes more like cotton. Both are v comfortable.
I don't know about other brands.
I have 10 pairs now, 4 heavy, 6 light. I could manage with 8, less than 8 was a bit of a stress with constant washing and drying, but 10 is easier, I will be getting Dd 10 pairs.
You have to rinse them in cold water before washing, which is no bother really. I will get Dd a wet bag for school/sleepovers and she can rinse before she gets home.
