Dual mode HR strap. Which mode to use ?

I have a HR strap that is compatible with both ANT+ and Bluetooth Smart protocols. As the Vivoactive can connect to both, is there a favored (least energy?) protocol ?

I don't know about power efficiency but with a Wahoo Tckr X I got the occasional drop out with Ant+ but BT was always solid.

I'm not sure what is better. I use ant+ as it seems to connect faster, no drops, batery 5% per 1.5h of workout (no gps). I have GEONAUTE chest strap.
