I like that it has been very easy to integrate into most themes, without having too many plugins or messing up things which are hard-coded within WordPress itself (which is great).
Honestly? It's still good for me even though we've moved away from using WooCommerce as our primary ecommerce solution - so not sure what this plugin does anymore now they have taken over all their own codes! Nothing really right off my end; but then again everything works well enough already in terms of how its integrated via standard WP functions/plugins etc..
