I switched from WC Vendors to Dokan because of some features DOkan had that WC did not. I was skeptical at first because of people saying Dokan Support was not the best. WHen I made the switch I quickly found this was not true. The Support Team has went above and beyond to help me fix bugs and help me with knowledge to customize my site to how I want it to work. I just wish I would have started with Dokan in the first place!
I highly recommend Dokan to anyone who is looking for a multivendor platform.
