The verdict
For a small B2B team that wants a marketing site it will keep improving, I'd pick Webflow. Every B2B site I manage runs on Webflow, I can spin up campaign landing pages in hours, and I would choose it again. If you need a site or a small shop this week and have no one to learn a design tool, I'd pick Wix. It also fits if you need built-in bookings. The Webflow cost is time to learn, plus fiddly budgeting with separate site plans and workspace plans. If you start on Wix and outgrow it, plan on a rebuild rather than a migration.
