Adobe Photoshop

An = Animate, makes HTML/SVG/someOtherFormatI'mForgetting animations. I haven't used it much but it was fun and intuitive enough for what I did with it.

Substance = Haven't used it/don't have the skill set but I think this is 3D modeling.

Xd = Experience Designer, I think. UI/UX things for web apps and such.

Au = Audition, yeah that's audio. I've used it in basic ways and it was straightforward enough.

Pr = Premiere Pro and Rush, video editing. I quite like them even if they are a bit fucky.

Bridge = I'm too stupid to get the point of this one. It basically organizes your media assets for projects, but...I also that that was what the CC app was supposed to do, so I assume serious people use one and the rest of us use the other.

Dw = Definitely Dreamweaver. I also thought it was supposed to be sunset but who knows. Some people like its preview features for sites they write...I guess because they don't realize they can get that without paying for it.

I've either used or still use some of these to some degree, though I'd hardly consider myself able to distinguish what's best-in-class for a professional. I use them because my job pays for them.

I do always find it funny how weirdly confusing products for creative cloud vs. experience cloud are. Lots of overlapping features and missed opportunities to integrate better, and then there's random products like Captivate that don't seem to want to be claimed by anyone.
