buying used:any diff in old and new fb style?

[merebella]

I'm looking to buy some used medium fuzzi bunz. Many that are for sale are the old snap kind instead of the new snap (I'm talking perfect fits, not the one-size). Is there any reason not to buy the old snap style? Is the difference only cosmetic, or is there a functionality difference?

Thanks!

I have the old style, and I've had no issues with them at all. Even when the new style came out I continued buying the old style from the outlet because they were cheaper.
