A directional tray is superior for sure.
I had one in a big Ford that I took to Nordic Ware , a manufacturer of cooking pots , pans and stuff and had them teflon coat it for me.
The guy who worked there thought it was cool and did it for nothing.
I don't know exactly what difference it made , but it sure shed oil in a hurry , which had to help drain back.
And the flat slots on the tray itself , I made them louver like in the direction of rotation to help both catching oil and draining back.
