I have never been convinced that any brand of spark plug was better than any other. If you get the correct heat range and reach, they will all work. I am currently running some Autolite's that were on sale for $.99 a few years ago. $5 race plugs won't improve how your car runs.
The only brand of plugs that I have ever had a problem with was Champion--25 yrs ago. I had 2 of 8 new ones that were defective.
That being said, you can not go wrong with AC Delco it you want to stay original.
