There is only about 1% difference between the oil and dry filters far as capturing particles so no worries there. However, oiled filters must be cleaned regularly and you must be careful not to apply too much oil lest you send the extra oil material to the MAFs and ruin them. I'd go with the dry filters and replace them regularly - less worry andless work.
That said, cold air filter systems have an extremely tiny effect on bhp (5 - 10 bhp) at full throttle only, performance, or mpg. All they will do is make the engine 'look' more powerful. Since I don't go about showing my engine bay to people, I consider CAIs an expensive, purely cosmetic modification.
The factory intake system was designed by engineers and the ho-hum looking plastic intake piece that sits at the front was already designed to provide the optimum amount of air.
Cold air intake is a contradiction in terms. If anything, the air that enters your engine through the CAI is warmer, not cooler than factory set-up due to the simple fact that the CAI filters sit inside and next to the hottest air in the engine bay.
If you want the 'look' of power, go for it. But if you want to actually have more power, get a tune + the CAI.

Assume you would need a tune on either one of them, but I'm sure you do on the Stillen.

Both of these systems sit outside of the engine bay, in front of the radiator.
There will be a performance gain with a proper tune - just make sure to collect baseline numbers.

For OP - Since the M37 engine bay is slightly longer than that of the G37; I'd go with the system that allows the easiest modification (a longer silicone joining tube). I saw the picture you posted in the FB group, but I wasn't able to respond at the time...one of them had the silicone tubes going on a longitudinal section, that would make install way easier.
