HonestlyI have come to like the Ring Motion Sensor G2.
They are Z-Wave 700, have really good range and when setup properly seem to be sensative. They also use standard batteries so you don't have to do anything special to provide power. Two double AA's provided power for 1 year.
One of the things I look for is also detection range which is also nice with the Ring Motion sensor G2
I have also used Aeotec Multisensor 6 and haven't been impressed with it. The documented range isn't that great, and neither is the angle of detection.
I also have the new Zooz 4-1 multisensor and so far it has been good. Based on it's documentation it should have pretty good range and works well from a corner. It is battery powered, but uses lithium ion batteries so won't be as direct to replace, and since it is my newest motion sensor can't speak to it's longevity with batteries.
Lastly I also have a Smartthings motion sensor from several years ago. It has worked pretty well and is by far the longest running motion sensor I have. It uses CR2450 batteries and though the sensor works pretty well i have to admit I don't like the batteries. I have seen recent reviewes discussiong these batteries and it seems there is a large variance in the quaility of these and other similar batteires by supplier.
My direction would be to use Ring Motion sensor as the first choice if motion detection is your main prioroty. If you need the other sensors then maybe the Zooz sensor. The aeotec only if you really want to avoid batteries altogether, just be sure you pair it properly.
