Don't know anything about the other church but WH at CoC has platform standards that would put him pretty much in the middle of most UPC churches. And only got out of the UPC a couple years ago.
It wasn't until very recently that he had men with facial hair on the platform. (Like the UPC). I have never known a man with facial hair to get behind the pulpit there.
By mainstream Christian standards he is very conservative.
He himself would be inconspicuous at a UPCI conference. Clean cut, always wears suit and tie on Sunday.
So like Sherri said, "no standards"? get real.
Last I heard he was even still an ardent three stepper. But I guess in the grand scheme of things some would contend that is a recent fad or religious fashion.
