The fact that it has everything you need in one place, without having to make multiple connections with different companies or people! It's great for getting your content out there more efficiently than if we were doing all of this ourselves (or even hiring someone).
I cannot think of anything bad about canard at present time so not much feedback - however, they are always updating their app/platform as well which helps ensure customer satisfaction over years down the road. If anyone wants an easy way to get high quality images used across platforms like Instagram etc., then use them! Very efficient service when it comes to marketing our clients' products online.
