Competitive Edge:
Superside: Their service as a whole is pretty tightly wrapped. There isn't a level of transparency that the company has. You have to schedule an appointment with their team to full understand how they might be able to help you and your business.
Penji: Full transparent with pricing. Penji shows off the benefits and how to properly submit and communicate with your design team.
