OneDrive and OneDrive for Business used different client, the "Current" OneDrive for Business is the "groove" client, it basically a simply file scanner and sync to a Sharepoint Document Libary, it is terrible (This is the same Client that is Integrated into Office 2016/2013 as well... awful)

the OneDrive "Consumer" client was/is based on the orginal Live Mesh product that MS bought

Last year MS announced they were merging the Code Base and Having OneDrive for business operate on the better OneDrive for Business Client, this is the Code name "Next Generation" Client for OneDrive for Business.

Dropbox clients is still better than both of MS offerings however.

You got that backwards. Mesh is the good client, groove is the bad one. The next gen one is the consumer client getting sharepoint support.

Currently, right now, mesh can sync OneDrive for Business but not OneDrive Groups.
