Spark Plugs: NGK or Denso?

I've always used NGK and I've never had problems. Doesn't prove anything but it's enough for me to keep using them.
 
I read that someone changed their factory plugs on a Honda V6 and one side had Denso plugs and the other side had NGK plugs.
I read that all manufacturers, including Honda, had supply chain issues during Covid and resorted to alternate suppliers. Some on BITOG indicated that you might get NGK or DENSO replacent plugs at the Honda dealership now.
 
Our TSX came with 2 of each. I have been leaning towards Densos lately due to Amazon fake NGKs.
Of course that's not NGK's fault. I can get Densos fast and fairly cheap at Autozone nearby.
 
I had Densos as OE on my 2009 Accord. Both NGK Laser Iridium and Denso Long life Iridium are great. I'd use whichever on a Honda!
 
On my Lexus, I bought aftermarket Denso.

Interestingly, NGK came out, from the factory in Japan. I had expected Denso to come out.

It likely doesn’t matter, they are both well known.

I’d check the forum for your vehicle to see what other owners say…
