Pros: Very fast. Free of clutter and ads both. Can be customized.

Cons: Extension compatibility is not perfect. Default interface requires some getting used to.

Pros: Multiple effects are offered. Perfect for those with little technical experience. A "scary voice" effect is offered. One-click recording capabilities.

Cons: Requires a good deal of bandwidth. No customization options are included. Essentially does nothing more than change the pitch of a voice. Constant rating requests can become bothersome.
