I've tried both the quatro and the super-plus. I'm a chronic bed-wetter and often wake up totally soaked. I do like the fact that both come in a "regular" fit, as I'm really in between a medium and a large, where often the lg sizes are too big and simply do not work. The regular size is perfect.
The quatro's are very thick and I hate that. It's frustrating enough that I need to use something for this issue and prefer anything as thin as possible. I think quatro's are overkill and as I said, I'm a heavy wetter. I tried the super-plus and I have had no issues. They are thinner, but not as thin as the total-dry I typically use. But, they are a good overnight protection and I have not had a leak.
For men, there's plenty of padding in the front and sides, so I have yet to experience a leak.
The only down side is that you have to pull out the leak guards a bit as they are stuck from the manufacturing process. But it's not a big deal.
HPFY sales both level's and you can try them for a small fee.
