The ease of use! I love how easy it's made my life as developer without having much knowledge about web programming. If you have some basic coding skills then your in for alot less headaches when using umbrido cms system (which i've been doing). Nothing really that comes across mind other but maybe try out their support team if they are willing or able help answer questions from beginners like myself.. Easy to use and customize, built in media library makes it easy to find content. You can extend some functionality of Umbraco using c# code. It's great for managing large websites and making them more interactive. I dont have anything specifically against umbraco but if you are looking for a product that provides all core features then you should consider other products. We needed something that gives us the option to do our own customizations without having to rely on third party services etc.
