The cheap cast sliding dropouts are not so great in terms of preventing the insert from slipping in use.

Paragon rockers are good, if you get the Titanium 12pt bolts with them. The steel bolts that come with the dropouts do not hold up to the torque necessary to prevent the drive side from slipping forward under heavy pedaling loads, such as climbing while standing. The hex in the bolt will strip out before you can get them tight enough.
