Qolsys S Line Smoke Detector vs. PowerG

I’m planning a new Qolsys IQ2 system and am trying to decide on smoke detectors. Is there any reason not to use the PowerG models over the S line ones as the wireless signaling appears to be more robust? Thanks.

The Power G models are a bit more expensive, but if that is not a deciding factor I would say no, go with Power G if you are at all concerned about range.
