I don't use Adobe personally, but my husband does daily for work. I can tell you that recently he signed up with some local agencies to get additional free lance projects and the rep he met with practically squealed to learn he was not only using Adobe, but the latest version (SaaS). She said he was the first one out of her last 14 interviews that did and that it definitely would make it simpler for her to find him additional projects based on that alone.
We both use several programs for editing (I use Gimp because I'm not using it that often). And would say if you're in a design industry it's worth it, if you're using it occassionally and not doing anything that you'd be getting paid for and needs to be a more specific current version it's not worth it.
