Microsoft 365 is not a viable business proposition

AGW3RT 

Windows Enterprise has additional security features which you can compare here:

e.g.Credential Guard, application guard etc

Windows 10 Ent that comes with M365 gives you the right to:

- Install on up to 5 PCs

- Be used in a VDI environment

- Includes Windows Virtual Desktop rights

M365 E5 provides:

- Microsoft Defender ATP

- Azure AD P2 (increased logging for example)

- Azure Identity Management P2

- Azure Privileged identity management

- Conditional Access

- Trusted Ips

- Advanced MFA

- Cloud PBX

- Cloud conferncing

- Cloud PSTN

M365 is a package. It is not just Windows Enterprise alone. If you have everything you require then great. I happily pay for M365 E5 for Defender ATP alone, which is fully worth the additional cost to me.
