It's been a few months since I utilized Magento in a project, but I was very impressed (from a end-user perspective) with its UI/UX and feature set. It's based on the LAMP stack and has a very active community and a variety of plug-ins. The downsides were that it is a little bloated, and the code isn't extremely well documented or developer friendly. Of course that was a few releases back, and I'm sure a lot has changed since then, but I would definitely recommend you at least see if it meets your needs.
