Jakam,

Tucks are the same thing but smaller. The Prep-H ones come in a large, resealable pack with 50 or so wipes, and you can buy them in a box individually wrapped. I buy them both ways and use the individually wrapped ones in situations where I need to be a little more discrete. Wal-mart has a generic ones too but I do not like it as well as the Prep-H ones.

The only advantage with the Prep-H over Tucks is size. I like the margin of error I have with Prep-H.
