Is it worth upgrading from SyncBackSE v6 to v7?

[gba]

I am evaluating a fresh copy of SynchBackSE v7 on my new Win10 machine. I have been happily using v6 for backing up data to external drives under previous versions of Windows. I am not noticing any major differences with v7. Does anyone have an opinion as to whether or not it is worth spending $40 to upgrade?

Thanks in advance for any advice you may have.
