Welcome to Discussions, msaafi2
I don't use either camera you mention, but, depending on your specific needs, either camera you mention can work for you.
The "quality" of cameras is subjective, so I suggest that you do some local shopping to see how any candidate replacement cameras look to
you. Having decided not to repair your iSight, you do
not want to be surprised by the image or lack of features from a new camera that you might find very different from the iSight you used for a considerable time.
Ask for demonstrations of each camera of interest. Be sure to try every software application that you will use with the camera. In addition to giving you a look at the quality of the images that individual camera models, the demonstration can also give you a clear understanding of other considerations that may be important to you such as compatibility with the applications that you plan to use (for example, iMovie cannot record directly from any external USB camera), whether you will also need to buy a separate microphone, etc. What is important varies from user to user, so pick the one that meets
your needs.
Others may be able to offer their impressions of the "quality" of the webcams about which you enquire. I suggest that you use such information as one input to your purchase decision rather than its sole basis.
Please let us know what you select and what apps you use with it. That info may help others who are also considering new webcams.
Cheers,
EZ
