I don't know which came first, but I saw it a bit differently. The Ram mounts to the body and includes a real solution to the crankcase vent and a radiator cover and plug for the old inlet hole. Vararam just sits on the throttle body and gives you a cheap vent cap to dangle somewhere, and I saw it as a cheap knock-off. Both will probably work about equally well initially, but Vararam may not age well. You get what you pay for, my $.02.
Vararam has been around for a long time. They are popular in the 4th gens. I'd say at least 10 years if not longer. it doesn't create any issues.
As far as the vent for valve cover, it's a filter that does exactly the same thing as connecting to airbox behind the air filter. All you need is filtered fresh air. Only reason it's connected to air tube from factory, and by Mopar on RamAir is for emissions reasons. Can't have the crankcase venting to fresh air if you want to keep EPA happy. So calling how the ramAir box connects a "real" solution just shows you don't understand how the PCV system works.
No need to plug the old air horn to factory airbox. That's just an extra part that adds cost.
Radiator cover, it's not that difficult to just trim your factory one for the Vararam. They provide instructions, and you have a little freedom to trim it as you like. I chose to keep the RAM lettering in mine. Varam gives you the old school Mopar look. If you like modern plastic look, spend more for the ramAir. They both look good in their own way.
