There are often several add-ons that have similar features. To figure out which is right for you, read the entire description of the add-on and view its screenshots. If there are still several in the running, read through the add-on's ratings, user reviews, and statistics to see which is most liked by other users. Remember that you can also just try out both and see which you like better.
不同的附加组件经常会有类似的功能。如果您想弄清楚哪个才是您所需要的，阅读附加组件的完整描述并查看其屏幕截图。如果经过您的挑选仍然还有几个不分上下，通过查看附加组件的评分、用户评论以及统计信息来看看其他用户更喜欢哪个。请记住，您也可以每个都试试看，来决定您更喜欢哪一个。
