Hello. This is my first post here. I've been a long-time lurker.
I use to use AC-Delco oil filters on the GMs I maintain. The new E-Core design might be OK, but I prefer the classic style with the metal end caps. So now instead of PF-52E oil filters, I use Motorcraft FL-402 oil filters. I do try to grab the original PF-52 if I ever see any, but the Motorcraft version works well.
This leads to my question. How important is the design of the tension spring? I know that both AC-Delco, Bosch, and Motorcraft use a tension clip style spring and others like Baldwin, Hastings, and Wix use an actual spring. I think the clip may be a more superior design. I watched a bunch of videos today on oil filters just to see the internals of many oil filters. Here is one about a crushed Wix filter:

It kind of makes me think the oil filters with an actual spring might have the possibility of not staying level inside the canister and could lead to the above video.
I like Motorcraft filters. Good and affordable! I cannot see any great automotive oil filter needing to cost more than $7-$8.

Here is a nice article showing cut open oil filters and the different springs they use:
