Balsamiq has a built in library of over 75 built-in user interface components and 187 icons, as well as community generated plug-ins.
Pro Low-fidelity UI elements
All the Balsamiq UI elements are drawn by hand and have a really nice low-fidelity design.
Pro Usability testing features
You can link together pages to create shareable user demos

myBalsamiq has been built with teams in mind and has a variety of featured to support collaborating on the mockups:
Notifications - Real-time notifications to enable you to keep track of team member actions

Skype Integration - Easy to use Skype integration to host design reviews.

Pro Keyboard shortcuts
You can use common keyboard shortcuts like Shift to select multiple elements or to resize while maintaing proportions, F2 for renaming labels etc.
Con Stifling innovation
Doing anything that is not directly supported by Balsamiq's conservative component library is next to impossible. User is forced to think within the corset of yesterday's standards.
