I like that it's open source, so if there is something we need to improve or fix in future releases then anyone can do this for us! There isn't anything i dislike about WG at all - everything works as expected when using them (and they are very responsive). They have an active community of users who use their software every day which makes things better than most other products out here because you know your product will be used by real people with problems everyday instead just having one person testing once per year etc..
