As others have said the fact that Umbraco is so versatile is really nice. But it does take time to adjust to the XSLT's as Anders says.
However one of the things that keeps me so happy is the community and the helpfulness on the forum of Umbraco. You rarely find that in a major CMS system even tho its open-source.
