MDG is the better choice relative MDM on HANA platform?

Hi, experts:

We will implement CRM, SRM, Portal, BI, S/4 HANA.

All the new system will be based on HANA platform.

There are also have some legacy systems.

We want to manage master data in a central system for new and legacy systems.

We found 2 solutions from SAP: master data management(MDM) , master data governance(MDG).

On my opinion, MDG is more suitable for our scenario.

Reasons:

1/ MDG based on HANA. So, we can simplify our instruction.

2/ MDG will be continue develop for future. And more compatible with S/4 HANA, CRM, SRM etc.

Is my understand is correct?

I'm waiting your advice.

Thanks.
