To me the key differentiator in agile approaches is whether it's business-led or developer-led. If developers can decide on what gets done and when, then agile can work quite well, but to me that's just a pipe dream in most cases. Unless a company's sole business is software, and the financial health of a company is strong, developer-led agile is a hard sell for business owners, even if it leads to long term benefits. So what happens instead is business-led agile which in my experience is worse than waterfall, as you get constant demands for poorly defined new features, with tight deadlines as that's being 'agile'. In other words, agile has just become a stick for companies to beat their developers with. That wasn't the original intention, but I would suggest that's at least part of the reason why management types like the term 'agile' so much.
