I love that it can host multiple instances for companies that have worldwide operations and need pages localized to regions. I like that it offers a preview of the pages you're working on before publishing.

I like the delivery API; it provides a structured JSON response that works well for headless development. One suggestion from my side is to provide a secret key (or similar option) to set up a draft version of content in a headless setup. Right now, I’ve had to create a custom API and write some additional code for our client to handle this.

I use Umbraco for all my client websites because it's a great platform for building unique, bespoke websites. I appreciate its flexibility as it allows you to create whatever kind of website you want. The security is great because they are quick to patch security issues, which are usually few and far between. It's also a very stable and mature product. I like its scalability too. Additionally, I love its integration capabilities as it works well with various systems, including Salesforce. The initial setup for the large charity site I support was made easier by using Umbraco.
