Search in the reviews section of this site, although any reviews there are tended to be biased. As for a screenshot - what difference does it make? It all depends on what window manager you are using, and how you have set it up. There are ultimately not that many differences between distros, mainly just their package management tool and their installation. Slackware has a text-based installation, and it is relatively easy to use. However, it has been said that slackware is only for those who are experienced, although I would tend to disagree with that.
Where do you live? If you live in the UK, I would be happy to send you a copy of Slackware 9.
