I haven't actually noticed much variation between them. I think it's ST covering themselves.
They seem to read a few degrees higher than room temperature, but that's usually because the chip really is hotter if you've got it connected to USB and it's not sleeping. It'd be interesting to connect a DS18B20 up and run some tests comparing the 2 temperatures when the chip is asleep most of the time.
