I remodeled the master bath in my last house and used the paperless drywall - the only difference I noticed was that it seemed a little heavier than the normal stuff. I used standard drywall screws and fiberglass mesh tape for the joints, but I used the recommended mildew-resistant joint compound - I figured better safe than sorry...this was in upstate New York where it is very humid much of the time. That compound was HEAVY - not sure why.

The paperless drywall cut, went up and finished just like the standard stuff. The finished side of the drywall appeared a little rougher right after I put it up, but it was fine after painting.

In case you weren't aware, you should use cement board behind the tub/shower areas to 6 feet high just in case you get water infiltration; the paperless stuff only protects against humidity. I found some at Lowe's that had little styrofoam ***** mixed in with the cement. It made the cement sheets lighter and easier to cut and handle.

Hope this helps...
