I love that it's very easy to use and has many different options. The interface is so simple to understand that even a non-techie can figure it out quickly! I wish there were more templates available. It would be great if you could create your own. I also wish you could have more than one option in some of the fields. However, I do not dislike Plan Lab at all.
