It was being given away last year with a magazine, and I tried it before I bought Lightroom. In terms of manipulating images, lightroom has significantly more powerful tools that deliver more pleasing results in terms of colour and tone control. There is an erase tool that lightroom doesn't have and the latest version has a few more colour-changing tools too. If you want to do basic image processing then LR is, to me, the better tool.
If you're looking for basic image processing software then also check out DXO optics pro (free trial, and v8 is also free to the end of Jan IIRC) and Perfect Photo Suite 9 (free trial again) although PPS is MUCH more powerful than Lightroom with a greater degree of image manipulation, but lacks the cataloguing capability.
