This is not a very deep comparison of the two views or even the two tools, consider this more a look at what’s available. This is actually my first time taking a look at BrowserLab. Having access to both BrowserLab and SuperPreview I thought I’d share a quick visual comparison of the two tools. The onion-skin feature caught my eye, because not only is it an awesome feature, but the two tools had different results for the same browsers.
The browsers compared in the two pictures are IE7 and Safari 4 on OSX. Both tools provide service-based rendering of HTML allowing you to bypass the need to have every browser and every OS installed in the same place.
