Any difference between after market oval chainrings versus SRAM X-SYNC oval for Eagle X01 Crankset?
Do teeth wear faster or cause increased wear of chain?
Any other important differences other than cost?
Thank you.

Yes, the OE Sram tooth profile is really nice and will outlast any aftermarket chain ring by a considerable amount. AB are OK, but OneUp chainrings would need replacing after every chain swap so ~1500-2000km. The OE Sram is good for 3 so 4500-6000km.
