After some more testing I have concluded for myself that actually the “Hotplug” governor is the best (on my S905x box). It acts much like the interactive governor by going through all the speed steps but with the added benefit that it can shut off cores seperately. Also, while using the interactive governor I noticed some micro-stutter. Subtle, but still there.
So again, just put this line in your autostart file:
echo hotplug | tee /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor >/dev/null
You only need to run this command on the first core, the other cores are linked to it.
