The visual editor is very easy to use, even for someone who has never used it before! It's still pretty new but I'm excited about all that they have planned as well - like being able make your own themes (which would be awesome!).
There could definitely improve some things in terms or navigation options/features within their platform so there may not always seem obvious when trying out different features from other platforms such an Adobe Muse etc., which can sometimes lead me down dead-ends with my projects if i don't fully understand how everything works together first time around; however this isn’t much more than just using another tool rather then working through trial & error until its right? This does take getting familiarised wth though since at times certain functions do look quite similar across multiple tools egs.: Adding media assets into layouts vs uploading them individually via FTP / SFTP file.
