Hi,
Well, my point of view;
PRO's;
- Easy to make a simple slideshow
- Fully adjustable
- Free for (non)commercial use
- Downloadable and hostable on your own server. No dependencies
CON's;
- The slideshow you make has only basic functionality; info-hotspots and navigation hot-spots,
- The Marzipano tool is not "alive". No more upgrades. Some basic functionalities are missing (for example: target hotspot POV/Yaw/Pitch not avaible, but can be build if you have JS-skills)
- The Marzipano community is small
- Skills in programming/scripting are needed if you want to add specifics (for example: popups, youtube video's, etc). So not a fast workflow.

Good luck
