i've found that chevy's are almost always happy with ac delco plugs, ngk's are also good. i've put a lot of autolites in customer's rigs because they're the most readily available at the local parts house and they work but i have had several fail inexplicably. not enough for me to condemn them but they're certainly not my first choice.
I can't say I prefer any one specific brand But I always use what came in it from the manufacture and it has never caused me any issues. In some cases customers noticed the difference with new plugs and would call back to thank me or thank me on there next visit. Something that never happened trying to use Autolites.

i Used autolites NGK's and delcos. IMO delco is the way to go for N/A motors expensive but worth it. I run NGK's BR7EF at the moment only cause im set up for my 150 shot. but If i go back to N/A im putting another set of delcos in it. I ran a set of autolites for about a week and started having a rough idle and checked the plugs and two were fouled? Checked my tune and codes and nothing was off or wrong. changed to my NGK's and havent had a problem since.

I sure haven't ever had very good luck with anything but Delco or NGK's. I've tried em all pretty much, Bosch, Autolite etc....... and mileage always seemed to drop and overall the vehicle just did not run or idle like it should.
