Why dont you try and grab one of each? You can test them on Kane and then decide which ones are best for you...

Chances are you will like all of them - so it wont be a waste - and if you dont like one or two, then hey its about the equivalent of 2 packets of huggies which you were just going to chuck out anyway

I have bought two types and all I have really been able to do is pour water in them and see how much they absorb, and how quickly. Also tried to see how easily they would pour over the sides - but both seem to handle liquid pretty well!

I am thinking I might grab a couple of itti bitti d'lishes just for when the unit is extra tiny too....

sorry that probably didnt help at all!!
