Downflow VS Crossflow Radiators

YY1 said
My understanding is that a crossflow radiator causes the coolant to take more time to reach the bottom, therefore exposing it to more time in the airflow of the cooling fins.

The design of the crossflow on my Dakota perplexes me because the outlet is almost 1/2 way up the core, causing quite a bit of water to remain in the radiator when draining it to do work.

Why?

...and if that's true, that means it's also slowing the coolant down getting out of the engine, which you do not want. Best case is get the coolant out as quickly as possible so it doesn't have time to heat up. So it sounds like the cross flow isn't conducive in doing that. ........if that's true.
