What is best for others may not be necessarily be best for you. The best way out of this would be to make a note of the features you want in the CMS you want to work with. Having done this, you should be able to choose the right CMS very easily.
I would recommend that you use Ektron, since it is considered as one of the best CMS tools. The latest version 8.5 has a lot of good features added to it. The old indexing service, which often gave numerous problems, has been replaced with a better and latest one.
