Reminds me of that beer commercial....."Tastes Great vs Less Filling"

More importantly, the beer has to be COLD!

In the case of the "oil bath vs paper element " argument, I personally don't drive my jeep much in the Sahara, on the Steppe in Ukraine in the summer, Iraqistan or in the Dust Bowl in the US of A.

More importantly, if you do subject your vehicle to any of those situations for sustained mileage, I would suggest to you that either system will fail miserably without proper MAINTENANCE.

What ever works for you, its your decision but that nice, rebuilt Carter WO 539S will probably prefer the CLEANEST air it can get to avoid mucking up the internals! So, the most EFFECIENT of the two should be declared the WINNER here with an eye to saving your carb if you are likely to be running through the desert or driving in sandstorms or the like conditions.

I enjoy draining the oil and cleaing out the Oil Filter as it gives me the opportunity to put a few drops of oil on the starter bushing in the bellhousing.
Just like the Arny and CJ Mechanics do without hesitation.

Maintenance.
I live in the land of the moving dust cloud. In the middle of the cloud is a piece of really expensive equipment. Some as much as 1/2 million $$$. You know something is in there because the cloud moves back and forth across the field. Does not just drift with the wind.
Now days, all the high dollar stuff has paper filters. Usually two. The outer main filter and an inner safety filter. They work very well. When maintained.
50 years ago, all the same equipment ( only smaller and cheaper ) had oil bath filters. They worked very well also. When maintained.
Biggest difference, back then we did not have the EPA and oil was cheaper than paper filter cartridges. Common practice was to dump the used oil on the gravel roads ( that are now paved with recycled used oil ), in front of your home, to hold down the dust.
Also had a great side effect. Slowed the traffic down ! It was safer to cross the road to get your mail.
Now days it is cheaper to toss the paper cartridge in a dumpster and send it to a land fill than deal with waste oil.

There is a reason they use paper filters nowadays on virtually every motor vehicle made; and the engines last forever; they must work. I use the Fram paper element conversion in my GPW; oil in my other MVs. Guess what; Zero difference in performance.
