Higher quality, they usually are because they have to meet DOT standards. But for a little more money one can have the Mopar beadlock which I have, or the AEV Borah which I had and loved as well. The Borah is a great wheel, Hubcentricand very high quality, I just didn’t care for the offset so I sold them.OEM alloy wheels are very high quality in my experience, certainly higher quality than 90% of the cast bro wheels (looking at you, BlackRhino, Fuel, KMC...) that people buy for their jeep.
That said, I the "upgrade" from Jeep is purely aesthetics. I'll continue to rock my 22.5lb snowflake wheels
