The ability to track all aspects in one place, from product information through customer interaction with your brand or website! I like that it's easy enough even if you're not tech savvy at first glance but have no fear because they've got tutorials built into their platform so anyone can pick things up quickly without needing any training/experience beforehand (and there are plenty!).
It would be nice though having more than just price comparison included as well - perhaps an option where we could compare other metrics such us reviews etc? We use this primarily when looking around new products before purchasing them ourselves however sometimes using our own staff members' opinions too which helps give some insight about how customers feel towards certain items within different categories.
