I was inspecting them at Walmart and these two ecore filters from Champion labs look and feel identical. Anyone know if there is a difference? Filter media perhaps? The Supertech is about $3.00 and the ACDelco PF63E is $7.57.
ACDelco PF63E vs Supertech equivalent

If the AC Delco has not a silicone ADBV, I would roll with the Supertech. My wife used her PF47E equivalent Supertech for 8K and cold startup remained quiet - engine showed a clear dipstick for the usual 2K........ life iremains good with that 03' Malibu. That vehicle now sits in the backyard and driven once a week. Wifey wanted a new Hyundai Santa Fe and as soon as my grandson graduates, he will get the Malibu.
The PF63e has a bypass pressure of 22psi which is important for the 5.3 engines as they build pressure up evenly through the entire crankshaft before oil pump relief valve regulates pressure (whatever that does, I don't know). But the filter requires a higher than average bypass pressure - there's a technical service bullitan on it through GM - and if you're using a filter of say, 15psi, the filter can dump contaminates right into your engine, causing damage. So it's important that the Super Tech filter meets those requirement, if it doesn't don't use it.

Perhaps, or maybe not. It's possible the ST may not be as efficient as the ACDelco, or could be the same. It's difficult to get authoritative information on oem efficiency.
One difference is the ACDelco PF63e uses a separate poppet type dome bypass. Otoh, the ST equivalent uses a nitrile combo valve, ie., bypass and adbv in one. Imo, that's the bigger deal. ACDelco bypass design is superior to the combo valve design.
Isn't the ST equivalent shorter than the PF63e? x ref site says ST equivalent ST10060.

Great info! Not sure about the length.
Railrust, does that TSB also apply to the 3.6 V6?

PF63E's are a decent size … shown here next to XG10575 (but XG media is more 3D)
If you google TSB #15-00-90-002A it lists some specs for the PF63E.
98% single pass efficiency at 25-30 microns, etc
I would also worry more about the combo valve than I would about the dome poppet valve in the AC Delco. I'm running the AC Delco PF63E in my new truck. Much cheaper if you order them from Rock Auto too.

Is this another comment thinking that the filter bypass valve somehow effects the pump's pressure relief valve?

I'm not saying that, not sure that is the case. All they mention is the filter needed a higher pressure to help maintain consistent pressure through the crank, and a less pressure filter would allow contents to flow into the engine.

Link to this info?
Only thing the GM TSB basically says is that they went with a higher filter bypass valve to help prevent filter bypass events on cold start-ups because of where the pump's pressure regulator sensor was located.
With a positive displacement oil pump, the oil flow going to the engine will be the same unless the filter is so restrictive and clogged (highly doubtful) that it would cause the pump to hit pressure relief. Might happen at temps of -20 F or colder during a cold start-up.
But certainly, the filter's bypass valve setting has absolutely nothing to do with how the oil pump or the oil pump's pressure relief valve works.

Building on what ZeeOSix said.
It is my understanding when GM made the variable rate oil pumps, they wanted to ramp the oil pressure up quickly on startup. In other words, get the oil where it needs to be more quickly on startup. To accomplish this, they also used remote sensing for the oil pump's output pressure. In doing so, the design has a time delay between the actual pressure and the sensed pressure. When this happens on startup, there is a pressure spike which would cause the bypass valve to open in the oil filter. To reduce the number of bypass events, then GM began specifying higher bypass valves for their oil filters to be used on engines with variable rate oil pumps.
GM believes they are reducing engine wear by improving oiling at startup and reducing the number of bypass events.
I believe they are likely correct.
