The download file referenced by the link below contains free trials of both Editions, so that you can easily compare them within the 30 day evaluation period, to see which Edition best fits your needs and budget.
I don’t know when Adobe will fix the InDesign CC 2017.1 dot release crasher, but the current release of IDImposer now has a workaround for the problem. See the Download link below:
Then follow the installation instructions Here.
Once you have decided that IDImposer will be a valuable addition to your tool chest, and know which Edition you want, get your license Here.
P.S. If you’re curious, the Adobe InDesign Scripting forum has more information on the InDesign 2017.1 bug, at: https://forums.adobe.com/thread/2308052.
