I’ve created several e-commerce sites in Magento and can agree with the comments above. One of the major things you do need to take into consideration with Magento is that it is a beast of a program and needs Magento specific hosting to perform to its best abilities.

The other thing that isn’t touched on here specifically is that you should be more concerned about the server you are going to use as dependent on things like number of concurrent sessions and server security, you can’t just rely on out of the box virtual hosting. Also, you will need to tackle your servers and server providers ability to be PCI/DSS compliant if you are selling anything (regardless of whether you take payment on site or not)

In my experience, Magento handles security slightly more easily out of the box than WordPress. Also due to the number of updates, as already mentioned, plugin compatability can be an issue on WordPress, but Magento doesn’t issue anywhere near as many updates as WordPress. Saying that, within 12 months there will be a significantly different version of Magento coming out (version 2.0)

Finally, the one thing that is in Magento’s favour is that you need a lot fewer ‘add ons’ to create a good looking functional e-commerce site. For 4,000+ products, I would definitely recommend Magento over WordPress, but your server is just as important.
