Interested in allowing users on your site to rate products or other content? Overwhelmed by the number of similarly-named Evaluation and Rating modules? This article will show you what each node review module does in order to help make the decision on which one to use for your purposes a bit easier.
Node Vote Node Vote displays a "star" rating on each node, and allows viewers to click a "Rate It" link in order to provide a rating of their own, from 1 to 10. It also provides several configurable options, including which node types should be vote-enabled, whether users can vote multiple times, and whether a user is allowed to vote on their own content.
NodeReview
NodeReview creates a new node type called "review," and allows you to specify which node types may be reviewed (including reviews, for maximum recursive fun!). You may also specify "axes" for reviews, meaning that you can review different aspects of the node you're reviewing (price, storyline, etc.)
Note: NodeReview requires the Views and Voting API modules.
Simple Vote True to its name, Simple Vote provides a simple widget for rating any node from 1 to 5 stars. By hovering and then releasing your mouse over a star, you register your vote, and the widget updates to show the overall rating. You can change your vote at any time. As a result, anonymous voting is not supported.
Note: Simple Vote requires the Voting API module
userreview Another module which stores reviews as nodes, the userreview module allows users to rate nodes on a scale of 1-10, along with a comment. It tallies both the overall rating of a node, and also provides a breakdown of what each user voted. An administrator can specify which node types can be reviewed, and which roles can create and/or edit their own reviews. The module also provides a number of display-based customizations (naming, fieldset defaults, etc.).
Note: userreview requires the Views and Voting API modules.
Vote up/down Package
This module provides a simple widget for users to "thumbs up" or "thumbs down" a node, similar to the system used at sites like http://digg.com/. A tally of points is provided on each node, and a "votes" tab shows the individual users' results. By combining this module with others such as Voting Actions, you can allow users to promote nodes to the front page themselves once a threshold is reached.
Note: Vote up/down Package requires the Voting API module.
Voting
The Voting module acts very similarly to the Simple Vote module, in that it provides a "star" interface that you can use to cast your vote. It shows both the vote you chose as well as the average vote. It includes the source .fla file for changing the way the voting widget looks.
