Adjacency effects (i.e. increased apparent sharpness) does not get as pronounced when the film lays flat. I believe that adverse artifacts may occur as well.
Francesco and Jim, I think the apparent difference of opinion is caused by the distinction between tray processing and slosher processing. The PF and Summitek sloshers are very smooth surfaced and vented (sides, corners and bottom) trays within trays.

I have done comparison tests with tanks and sloshers and the results were virtually identical. With 8x10 and semi-stand development, my preference is the slosher.
