We've been using Adobe Experience Manager Sites for several months and it's been a mixed experience overall. Best for large enterprises and multiple brands but I think it would not be the best choice for small teams without much IT support or a smaller budget.

I've found AEM to be one of the most difficult and unintuitive content management systems I've worked with (compared to experiences across a few companies throughout my career, all with different systems). Though I'm sure the pricing and sales pitch are appealing, the day-to-day UX for non-dev users is clunky, buggy, and requires lots of training.
