Is a HomeKit temperature sensor better than a thermostat?

It's just different. Your thermostat is connected to your home's central HVAC system, while the HomeKit temperature sensor is connected to anything else you'd like to put in your smart home, from fans to space heaters. Plus, certain HomeKit temperature sensors have special features, such as humidity readings, water leak sensors, and air quality monitoring.

Do I need a hub for a HomeKit temperature sensor?

Some of them do require a hub, which is listed in the description, so be sure you know what you need before you purchase. For some HomeKit devices, no special hub is needed. But if you want to be able to set up scenes and automations or operate your HomeKit temperature sensor away from home, you'll need a dedicated iPad, Apple TV, or HomePod to be your general smart home hub. That said, more and more smart devices are utilizing Thread, which allows devices on different platforms to communicate.

Which of the best HomeKit temperature sensors should I buy?

In the market for a sensor with a built-in display that doesn't require a hub? Then take a look at the Eve Room with Thread.
