Blackboard and D2L

I think both of the systems are just about the same, I know I was researching pros and cons, and blackboard was claiming that D2L was stealing formats and the way they set up their learning tools. There is still an ongoing investigation and lawsuit going on between these to companies. Moodle and blackboard seems like it would be alot less secure than D2L. I think maybe because I am used to D2L already I am a bit biased but I do feel strongly that D2L is strong site for professors and students to use for giving quizzes and posting information about their classes. D2L is more geared towards College students.
