Which LMS do you use and why?

I work for a university that has us using Blackboard. Everyone on our IDS team knows how clunky and limited Blackboard is, but we are stuck with what we have.

I once heard it described as being like a trailer home whose owners, when the abode became outdated, built onto the existing structure rather building a new structure. Thus, there are hallways and stairways that appear to be useful but that lead to nowhere, and there is no fluidity of design.

It is a nightmare to change content in groups, for instance, as you have to make the changes separately for every single group. At times, this means making a single change to five or six different groups in multiple sections and the Master Template. Very inefficient! 

We are trying to add Storyline to our design team tools, but so far we have been unable to get permission to turn on SCORM in our courses. We've put in the request... so maybe it is on the horizon?
