You would be safer with the 256GB SSD.
I have the following large programs installed on my Mac and I am using 111GBs of my drive: MS Office, LibreOffice, Adobe Acrobat DC, Illustrator CC, InDesign CC, Audition CC, Photoshop CC, Steam (although the game library is on an external drive w/ my iTunes Library), and all of Apple's default free apps (ie Garageband, iMovie, Keynote, etc.).
As BasicGreatGuy said, you do not want to fill up your drive because it effects performance as well as you will want to have some room for future growth (if all of the sudden you want to start using Final Cut Pro for some reason).
