// EDITOR'S TAKE
Twenty feels closest to Copper day to day, with a clean modern interface and contact and deal records that sales people will actually update. EspoCRM is far more complete on workflows, reporting and email integration but looks a decade older, and Odoo only makes sense if you want the CRM as part of a much larger ERP install.
