I just prefer OEM plugs and Champion isn't an OEM for any big automakers.
Champion is still OEM for a lot of Kohler and Briggs engines. That's about all I use them for. No issues with them.
Japanese and Korean cars always spec NGK or Denso, and there is no reason not to use them. Old Fords (pre-modulars) were mostly designed around Autolites, and new ones use Motorcraft, lots of which are NGK-made. GM has ACDelco, lots of newer GMs use Densos. I don't know anything about Mopar or European stuff.
Probably nothing wrong with Champion, but there's just better choices in most applications.
It can't help can it? If the center electrode is not centered it can lead to misfires. It's an easy thing to spot and I have no time for Champions lack of quality control.
I’ve had champions in OPE or garden tractor engines. When replacement time goes, I put NGK in anything and everything. GMs, Fords, Hondas, BMWs, Polaris, Arctic Cat, Can-Am… everything any anything I own gets an NGK.

Not surprised...note that NGK makes two different lines of platinum and Iridium plugs. The 'oem' versions have thicker center electrodes and designed for 100k replacement intervals. They also make a more performance oriented version that is claimed to be 40k to 50k replacement intervals. Those have a finer wire tip. I had this explained to be when I called their tech support line a few years ago.
It was a surprise to me too. My older BMW, Toyota Tundra and Ferrari all came with NGK as OEM standard. Same with my ancient Kawasaki Ninja I have owned forever...
