It will depend upon if you'll want to have the control ring which would give you a similar experience to using RF lenses (physical location would be different; rear vs. front).
You can set the control ring to do different things such as adjusting ISO. So if you foresee using the extra mechanism to adjust certain settings, the adapter ring version would be a good move. It's almost the same exact size and just an ounce heavier than the standard adapter, so even if you rarely use the ring, it won't be adding extra bulk/weight to your setup.
One other thing to ask yourself... do you foresee moving to RF lenses in the future? Or just keeping EF lenses? If you're moving to RF, perhaps save the bit of money and go with the standard adapter. Over time, your RF lenses would all have control rings. But if you plan to just use EF lenses for the long term, I think the control ring adapter would be a better move.
