Is a Sonoff Motion sensor better than the Presence sensor?

Newb here. Bought two sonoff zigbee presence and one sonoff zigbee motion sensor as part of my first zigbee vibe.

I find myself using the motion sensor to turn on the kitchen light, and the presence sensor to turn them off, because the presense sensor seems too slow to react as an on switch.

It feels like a waste to have two sensors do one job.

Am I missing something?
