I saw a lot of SF projects budgeted and staffed in roughly the same way as you would SAP.
SF started with CRM and has been expanding to ERP, SAP is the other way around. Both are mainly Cloud/Platform-based offerings today, both feature multi-month certifications, high rates for contractors and lots of effort administering/configuring/customizing.
I expect in a couple of years they either turn out exactly the same or swallow each other.
