Which sensor to trust (BME280, BMP180, DHT21, etc.)?

Question

Microcontrollers

There are several sensors for the weather station: BME280 (temperature, humidity, pressure), BMP180 (temperature, pressure), DHT21 (temperature, humidity) without a large external case, there was also DHT22, but now it is missing and there is also DS18b20 (temperature).
I checked them all while working simultaneously for a day (BME280 + BMP180 + DHT21 + DS18b20). As a result, the differences in BME280 and BMP180 readings are small, 1-2 degrees in temperature and 2-6 mBar in pressure. But the differences with DHT21 are already greater, humidity from 10 to 30% on DHT21 shows more than on BME280, temperature from 2 to 6 degrees on DHT21 is higher. All sensors are located at a distance of 0.5-1 cm from each other. The documentation for the sensors indicates the minimum errors (0.5-1 degrees, 1-3% humidity, something like that).
Interested in which sensor is better to trust the temperature and humidity, who gives the correct values?
PS I read that DHT22 is more accurate and better than DHT21, but at the moment I don’t have it for comparison, maybe someone also compared it with it.

Officially, only he can be "trusted":

Make a check on the usual good thermometer and barometer
