Hey, nice blog :)
But, you missed mentioning another standalone multi-vendor eCommerce platform Yo!Kart (https://www.yo-kart.com/).
It is an emerging platform with 1000+ clients across the globe. Some of their clients even claimed that this platform is better than Shopify Multi-vendor. Check the review here: https://www.capterra.com/p/147559/Yo-Kart/reviews/2634335/.
I think this platform is worth mentioning in this list.
