Shop & Inventory Management

I’ve had a wix shop for a while; I have recently added Facebook/Instagram & Amazon.

I have used Multiorders to manage all my inventory the whole time.

I’m going to replace my wix store with an ecwid shop & ecwid has the capability to link all of my accounts just like Multiorders.

So my question is should I keep Multiorders or switch to ecwid & how good is the invintory management of ecwid?
