In short all filters are made the same just slightly different mesh screen.
Actually they're not all the same. You can watch a video on youtube searching how oil filters are made. I've taken apart many filters over the past year and they're all the same style in theory with different quality levels pretty much. Some have paper end caps, some have metal. Some anti drain-back valves are rubber and can fail after 3k miles, and some are silicone and last a very long time. Some of the bypass valves are at the bottom of the can(not so good) and some are right at the top where the oil comes in. And the filter media changes slightly with each filter, they all like doing it a bit different. Again youtube has a bunch of videos of people taking them apart.

Also, you will have no issues switching to a synthetic blend. Mobil 1 isn't a full synthetic oil anyways. It's also not the good of an oil either.
Actually Ac Delco low level filters are pretty poor quality. They're comparable to a fram or maybe a little cheaper. Mobil 1 claims to be a full syn and what would make you think it's not that good of a synthetic oil?
