Depends on the industry,Oracle Netsuite is similar to SAP. A lot of construction/professional services use Deltek Vantagepoint. Also Mircosoft Dynamics comes to mind.

Yeah, it really depends on the exact use case. And the availability of functional consultants with relevant industry expertise. SAP isn't great t project management, even if make-to-order works just fine, but that is still a manufacturing environment. SAP is also somewhat lacking in terms of logistics and warehousing (at least it was last time I checked / worked with SAP in that field 5 or so years ago).

MS Dynamics seems to have some good ideas when it comes to field services (I never worked with that, so). INFOR is rather good when it comes to project management and project driven manufacturing and planning. So, pick your poison, because no system will satisfy all you wishes, but the decent ones will satisfy almost all your needs, one way or another.

One of the big benefits of picking SAP is the huge pool of people with relevant experience, from developers over users (from simple employees over key users to super key users) all the way to those "controversial" consultants. And that across almost all industries, countries, regions and functions.
