Industries are about standards. Once there's a decent incumbent and it achieves critical mass in the field it's hard for anyone in the business to use anything else. I've never said that Vegas et al are better if you want a job in video editing. But for me certainly, it's just one of those things that I do as part of my work - and a pretty inconsequential part of that - so am not bound to standards. Nevertheless I need to deliver a decent product, so I use a professional-level product which generates results as good as the industry standard, which is for me easier to use.
