Thermostat replacement for 2019 Ram with 5.7

Looking for advice on which temp thermostat to install on a 2019 RAM with 5.7L engine. I was told that OEM is 203 degrees, but there are other choices that run cooler. Should I stick to the OEM spec one or install one that runs below 200 degrees?

Thanks in advance for your responses.

I would recommend staying with the OEM temp.... Some of your sensors work better at those temps... The Computer knows what its looking for....
Cheers.
