I chose the AirGradient[0] One. It's slightly more expensive than the aranet4, but has more sensors. It's open source, reports CO2, PM10, PM2.5, temperature, humidity, and more I'm probably forgetting offhand. Loaded it with the esphome firmware, so Home assistant integration is seamless. And since it's open source, when a sensor inevitably wears out in a couple years (like the PMS5003), I can just replace the sensor instead of of buying a whole new unit. Highly recommend it.
