You can make out the red lettering of the Stillen oil cooler on the driver side vent.

1 - to arid is keeping the car cooler and more efficient overall. The trans fluid is hotter than the coolant, so when removing the additional cooling overhead from the car, the car will run cooler.
2 - The aftermarket coolers are much better at the job. Also, the fundamental need is to prolong the amount of time the fluid is out of the trans, so it will cool better generally. Lengthening the lines by themselves, about 14" each, will drop trans temps pretty well
I wouldn't keep using the radiator trans cooler - it will only hurt, as technically the fluid is being cooled by much hotter water than air alone in the cooler - reducing efficiency overall.

The lessor of the two evils, and preference, would be to run it cooler than warmer any day. If you are FI - you want cool as can be to reduce the stress of the added power. There are several models to choose from = get at least the 1/2" to 5/8" version - the 1" is way overkill for our cars - unless your pushing over 500WHP, etc.
