Those are all great brands and great filters but something seems to be unique about the KIA/Hyundai engines in regards to their oil filter requirements.
In addition to the start-up rattle, I have also recall reading that some testing was done in high rpm operations and many aftermarket filter failed to meet the bypass requirements for KIA/Hyundai.
I do not think KIA/Hyundai is being malicious in a profit motive to say only their filters, just that nobody has built a aftermarket filter to fit their requirements.
Most of the aftermarket filter makers throw an equivalent Fram part # PH2808 to these engines because they fit and not because it is built to the spec needed to these engines.
It also does not help that some KIA/Hyundai dealerships throw on a cheap lube shop grade generic filter when people get their oil changed on either a prepaid maintenance plan the dealer offered or advertised as a "budget" filter change. This is more ignorance of those particular dealerships rather than anecdotal evidence that aftermarket filters are OK.
I think what is unique about the KIA/Hyundai TSB is that they have plainly stated warranty repairs due to what "they" deem is an incorrect spec'd aftermarket filter, will be denied.
I am sure people will throw out the "Magnuson–Moss Warranty Act", but that will be an uphill battle in this case.
While not a filter brand snob by any means, I have bought a case of the factory KIA/Hyundai filters and can say they are a top notch quality piece. While I have not dissect one, the TSB above gives a cutaway pic and shows it to be above average in construction.
