I found it a very useful program, especially for just viewing one code/theme/node in order to separate it. It does have a slightly quant feel with some features of counting and percentage covered for codes. I'm not sure how necessary that is, but you can easily ignore that.
The major downside for me was in how to approach it. I spent a lot of time restructuring my tree codes when I first got into it. Also, I spent a lot of time looking at the 'trees' instead of the 'forest'. Something about how my brain works and how NVivo was used, I sacrificed the bigger picture for the details. Don't rely on it 100% for all of your data readings, but learn how to use it to your advantage.
