I did a film output (35 mm full frame blow up done by CRT recorder) of exact same footage(medium and close-up shot of a person a la still photo portrait style) shot with Sony HDV Z1U in 1080i at 25fps interlaced and Panasonic DVX-100A set at 24p (29.97 interlaced). Prior to film output both were de-interlaced. The film was projected in a regular film theatre alas not side by side but one after the other. The Sony produced a far superior image in every respect - tonality, grain, film-like look, contrast. The DVX 100A looked very much like miniDV - grainy, contrasty, video-like.
