Yes (it depends), let me share in brief summary that I believe there is a case to be made several years later from when you originally asked this question that I believe its fair to revisit.
Based on my experience SAFe is currently best used by non tech and legacy corporations which typically experience the most challenge when looking to change to "this way of working" aka "being agile" or trying "scale agile" It a framework that I've learned is sort of scrum with enforcement of processes, event to extend visibility, coordination and alignment across a company.
Also, I agree with general sentiment that SAFe can feel somewhat prescriptive as well as use their training catalog as a main cog in their business model.
However, in the case of the typical companies that are looking for this framework as a solution to implement - it general supports the environment (e.g. upskill employees, support change management) in which it being applied in. hope that helps.
Examples of "Big Companies" that leveraged SAFe to scale agile Big Companies Leveraging SAFe:
- LEGO Digital Solutions
- Royal Phillips
Today, there are several other frameworks as well designed to support scaling agile, here are a few to reference and learn more about Scaled Agile Frameworks example 1 Scaled Agile Frameworks example 2
