When you sign in with a Samsung Account, services tend to be geared more to the device than the server - what I mean by this is that products like Google Messages, Drive, and Play Store all have their own ways of allowing which types of accounts. Typically Google will offer background checks in the form of multi-factor authentication. Ultimately, do what seems best for you, the user, but remember that having a domain Samsung Account configured with your Samsung device will free up a hassle of sign-in inquiries for future applications.. plus you can then add a Google account (yes, even the same email attached to the Samsung one) and proceed to other way of going about it.
