Which program to monitor CPU temp?

Okay .. what should I believe in here?

MSI Command Center says 36c on CPU
HWMonitor says 38c
Real Temp says 28c ..

That's a really big gap .. way too big I think! The difference is 10 degrees ?! What program should I put my trust in?

Thanks in advance!

If you look at the CPU temps on hwmonitor lower on the screenshot you will see the cores are 29°C there is different sensors on mobo's, just depends on which ones you look at. package vs cores etc..
