The natural place to start is comparing ERP products. But before asking which system is best, there is an earlier question worth answering: are you ready to evaluate ERP vendors effectively?

The better you can explain what your business needs, how it operates, what matters most and what constraints vendors need to work within, the easier it becomes to evaluate different ERP systems against the same business requirements.

If that information is not sufficiently captured beforehand, each vendor may end up doing some of the discovery themselves. That can mean repeating the same conversations and comparing proposals based on different understandings of your business.
