I took what I would like to call a gamble, or at least thought was, going with CS Cart in the beginning. 2.7 star rating from what i remember, don't remember the citing. Unless I am a complete idiot, which I very well may be, I have not had any major issues with CS Cart that I had with magento and wordpress/woocommerce before.
Woocommerce multi vendor was so terrible, I would wonder waking up whether or not I would be having a PayPal conflict that day and even be able to accept payments.
I'm not a developer, but as far as I can tell with add-ons, and the amount of devs you can get to help with mods, you aren't going to find an out of the box solution that won't ultimately cost you.
CS Cart is a bit pricey but I can say I am 110% satisfied with the switch I made and I wouldn't be doing what I do without it. The themes are what you make them... Also great out of the box!
My 2 Cents...
Also thanks to the CS Cart community for the support!
