Always the great debate betw these. For what its worth I have never read a complaint on a dynatrac set and mine I was extremely impressed with.. That being said 90% of the peoples ego who spend 600+ dollars on a ball joint may not allow them to write any kind of complaint against something they spent so much money on and "of course they are night and day difference and worth every penny!!" Now it seems Dynatracs may be a great option and if your like me always want to do go 1higher in performance and reliability if that is not the case It seems OEM are the way to go for the most reasonable, reliable and happiest client pool.
