Wow you put them under a microscope 
Isn't the Ph7317 the lowest tier filter for fram? And M1 is a premium filter? Comparing a $3-4 filter with a $9-10 filter?

So what is your observation?
I see things that rule out direct comparisons.
I see things that rule out direct comparisons.
I like Fram, but the rough around the edges quality reminds me of Hi-Point firearms.
Looks like the die is wore out on the Fram. IMO it should not leave those burrs.
Just my $0.02
Just my $0.02
And what exactly is the take away in this comparison?
That you can find filters without all the burrs and sloppy assembly. Companies need to take some pride in their products instead of spitting out stuff like pictured above.
Just how do some rough edges on the inlet holes hurt? How about cutting them open and looking at the other side of the inlet holes for sharp edges and burrs that the ADBV may make contact with ... that would matter more.

Here's the inside of the base plate on a Fram I cut open a few weeks ago and still had it in the garage. There's a reason they punch out the holes from the inside out. Base plate hole edges that the ADBV can contact are smooth and burr free.
It looks like on the fram you see the bottom of the punching, the other ones you see the top. That in itself says fram isn't trying too hard with that filter, but if you look at the other side of the other ones they may look the same?
The Mobil 1 has a "beauty plate" skin over the baseplate ... Purolator does the same thing.
None of the metal burrs are going to dislodge. If You couldn't make them break off with your finger nail (I've tried, they don't) they won't from oil flow. And if one did, it's going to be caught in the media anyway, without damaging the media.
Would it be acceptable for a $20k Corolla to have mis-aligned doors because it is $60k less than a Lexus LS 500?
I am not pointing out the cost but the manufacturing of each filter. Does a door open and close while being mis-aligned? Sure. Would it be preferable to have the door aligned? Yes.
I believe the XG7317 at $9 uses the same base plate.
Yes I agree, somooth eges wher the oil exits have no impact on flow or filtration. It does matter in the oil pump orifices and galleys, but not in the filter. This is like saying the box the filter is junk or badly made, so the filter must be junk
Not the greatest-but I would rather have them on that side than ALL the Mann & Hummel ones that have them on the inside & damaging the ADBV. I would agree that First Brands has been doing some things detrimental to the value & quality of Fram oil filters-but I wouldn’t put this high on the list!
