Looking to Implement a CRM for up to 15 users including Sales, Marketing and Services

Hello everyone, our company is planning to implement a CRM to manage Sales, Marketing, and aftersales services. Our customers are both B2B and B2C, and we also have over 15 sub-dealers. Currently, we are comparing Hubspot and SalesForce. I'm not quite sure which one is the best for us. We also have ERPNext which will be integrated with CRM. Any suggestions?
