+ Pros: easy to install, use and configure (may be because of less config options). Being a native Joomla extension and only compatible with Joomla 3+ make the code more readable and understandable for me. It is quite fast too.
+ Cons: less config options mean less customization and not yet has an integrated payment gateway at the time of this review.
However this project is quite new and I hope the developers can address these cons in their upcoming versions.
