I think they are all *intended* to reduce tension and/or grinding.
I don't think that the usual full upper plate guard reduces the
clenching tension. I've seen data that suggest it may increase the
clenching. It does protect the teeth from grinding.
Other type designs such as the "NTI" seem better designed to deal
with clenching and to reduce the actual muscle tension. There's a
picture of an NTI at

Biofeedback seems like a great way to address many such problems.

My lower, hard, biteplate increases my grinding, while protecting my teeth.

This is very interesting! I had the most unbelievably bad migraine the
first night I wore my biteplate; it had to be filed down on one side.
