The water-oil cooler is a little cheaper and it gets the oil warmed up faster.
That's the "why" why Mazda switched.
Note that even the GSL-SEs have a fairly poor oil cooler location - it's hard for the air to go through the oil cooler because it then has to go through the radiator, so it's easier for the air to bypass the cooler entirely. (Of course, all oil coolers DO have thermostats in them, but still... what a half-*** idea to put it in front of the radiator)

At speed there is sufficient high pressure to ram air through 2 levels of radiator, just as 3 core radiators are not noticeably less able to cool coolant than 1 core rads.
At low speeds with only the fan doing the work it's a bit trickier, as the oil cooler in front of the rad has only about 1/4 of it's surface area within the lower part of the fan's sweep area, but @ low speeds and idle the fluids aren't being heated as rapidly.

I would recommend it for everyone. Such a easy mod to do. If I knew it was that easy I would have done a long time ago.

How about the hoses? I've got an 85 GS and I've noticed that the 79-82 hoses look a little shorter than the 84-85 SE hoses. I'm using the cooler that mounts directly under the radiator, so which should I use so that they will reach?

If you have an 85, you radiator is too tall and will not allow placement of the oil cooler under it. You will have to mount it slightly in front of the radiator, just like a stock GSL-SE oil cooler.
I am pretty sure you will need the longer GSL-SE style oil cooler hoses, or have some made.

if you change to an 81 core with mounts for the cooler those hose are the same length. cause it is pretty much the same car. one note though if you change to the cooler you have a few things to change like you need the oil filer mount off an 81 engine, some heater hose to reroute a hose, may have to remove ac to get the hose on the front, and alot of tlc.
