In my opinion, WooCommerce is simpler and is suitable for those who don't have much development experience. Magento, in addition to being much more robust, requires complete development knowledge in order to maintain itself.
magento is certainly much more robust and therefore it consumes more resources, you need a hosting to manage the hosting, maybe with nginx, redis to get a good performance.
The two do ecommerce work, the issue is robust and business size. vlw
I don't think it's worth trying this theme for magento 2, this theme hasn't been supported for a while and in the last version that says it's compatible with magento 2.3 it's having some problems
