From a filtration and water separation functional perspective, the OE filters on your ram are in no way inferior to any spin on filter or water separator conversion using elements from Donaldson, Baldwin, CAT, Wix, etc.
The only advantage is price. If you're looking at $50-60 per Mopar element from Genos vs $25 per spin-on donaldson from crossfilters from your local dealer, how long will it take at $30 per filter to pay off that conversion kit? The diesel bro pickup truck aftermarket is always willing to sell you something to sell a non-problem.
Personally, I'm not willing to give up WIF sensor function. (Some of the aftermarket kits use filters that don't have the WIF sensor in the bottom of the primary filter/separator.) Just buy a few sets of the Fleetguard/Mopar elements during a Genos black friday sale and don't worry about it. Keep a spare set in the shop and a spare in the truck/camper and move on with life. Buy the necessary tools, catch containers, drain tubes etc to do the change and keep them in your tool kit, preferably in the truck. For me that's a set of filters in the camper along with a WIF sensor wrench and strap wrench in the truck, along with the 1/2" wrench set that is already in there for tire changes, that is sufficient for the front housing cap. (Your truck has a different setup for the rear housing.)
If it was an older truck and we were adding filtration and/or lift pump functionality that was not present from the factory, different story. I'd have some very specific filter recommendations for you.
EDIT: FWIW, the CAT 1R-0750 fuel filter became famously awesome because it had a 2 micron spec, which was better than the other filters on the market. But then the ISO specs were released and that spec changed. The CAT now carries similar specs to the other synthetic media fuel filters. It's cool because it's yellow, but you can do just as good with a spin-on from Baldwin, Fleetguard, Wix, or Donaldson.
