I know that generally comparison questions are seen as primarily opinion based and people are very quick to dismiss them.
However, as a long time pro, I can see circumstances where such comparisons are valid. For example when it comes to core functionality, scalability, security, extensibility, etc. etc.
Are we going to have clear guidelines on how much slack to allow on these types of questions without getting overzealous in just shooting them down and marking them as off-topic? Although it usually comes from the relative newcomers, I know that many pros switching solutions will have these questions as well.
They want the benefit of experience and not just what is listed in the "features", that's what we want this to be right? Professional quality solutions?
