I like the 3-ply stuff.
I once found some nice aloe vera 3-ply stuff that was like wiping your butt with a silky cloud. Super soft and very nice. I've not been able to find it since though...
If you happen to live in/near an area with a Costcow (probably US only) I have to say I like their brand of TP. Though for some reason all Costco brand stuff actually goes by the name of Kirklandw.
I'm in a like/hate thing with Costco lately.
The quality of many of the products they carry has been slipping badly, and the quality of their fresh food/produce has tanked completely. If it has no expiry date, then it's likely ok. Expiry date? Forget it. I'm guessing that they're buying up cheap stuff that's almost expired at cheap prices and stocking that -- had a few problems there.
But they don't carry the kind of TP I like here (Melbourne). I'm pretty sure that I used to get it at the Costco in Yangjae, Seoul. (Their produce was usually good, except for the onions which always sprouted too quickly.) Come to think of it, I think it was a Korean brand... Not too sure... Aloe vera 3-ply. Lovely stuff to wipe the old tush with. The only thing better would be <insert the name of someone you hate, like a politician, here />'s tongue.
