I always open the box, and look for a "reverse flow seal" that is made of softer (red) rubber and a non-stamped top plate. The stamped plates always have buggers on the back of the holes that keep them from sealing well. I consider these backflow preventers to be critical in getting oil to your lifters and valvetrain quickly during startup. They help to prevent "drainback" when the engine is shut down. I like the grippy on the frams, but will only use their silver filter. Since I have a GM, that usually leaves me using Bosch, Silver Fram, or Mobil. Always liked the Motorcraft when I was a ford guy...
If you open the boxes in the store, you'll quickly see that it looks like only one or two companies out there make filters...

Synthetics....
"Better" for what? For how long? I'm with you , here. Good oil is good stuff.
I , too , had the same questions about oil filters. Many brands, many prices, can't see inside.... Fram seemed safe, so I went with this....
Then, I met Google! My whole world opened up! When I asked Google about oil filters, she led me to a guy who had the same questions I had...and he took the time to cut his many samples open...and check the paper elements for lots of things, checked construction, checked oil from each...and on and on. This guy was great! I'm so sorry the URL is gone in my disc crash... but Google knows.
Long story short...the absolute best in the (American) world is also the cheapest! He had no reason for this...but he wasn't playing favorites. The brand? Pur-o-Later ( "pure oil later") , made the same way since forever, same filter paper ( low micron), potted paper ends( not crushed like some), good, simple construction throughout, and great price! He sold me! Why should I pay more for less filter?? Incidentally, Fram wasn't so great. Surprising! AC was OK... But there're not cheap!
And, several companies make oil filters. The just take the same shape/form ( money talk$, $upplier$ listen).
Have a nice day!
