I would go with FlatpanelsHD's (Avant) settings, too.
Lately, I've been using the settings in their BV11 review, except that I'm using the Adaptive picture mode, with color temperature set to 24, for everyday TV viewing. The lowered color temperature with Adaptive mode brings the picture a little closer to Movie mode's color temperature, but not quite as warm.
So if you find the Movie mode too warm (reddish), try FlatpanelsHD's settings together with Adaptive picture mode, and set the colour temperature a little lower from the default.
For blu-ray, I use FlatpanelsHD's exact settings.
Of course, you should ultimately settle for the settings that look best to your eyes. What looks good is always subjective and individual.
In any case, setting Sharpness, Contrast Enhancement and Noise Reduction to 0 is always a good starting point. That removes processing that usually brings most of the unwanted artefacts to the picture (especially for high quality sources). If you find regular TV picture too soft with Sharpness set to 0, try increasing it in increments of 8, i.e. 0 - 8 - 16 - 24 - 32 (32 is the default value).
It's also good to let your eyes get used to any settings you try (leave the settings on for a few hours / a day), instead of making adjustments too frequently. Your eyes might go nuts 😁 (meaning that it's hard to tell which settings actually look best).
