Default Drive Belt and Tension Idler

I hope this doesn’t seem silly, but to eliminate 2 possible sources of engine “chirping” I’m replacing my drive belt and tension idler. I’ve done some research and there seems to be strong recommendations for the Goodyear(now Continental ) Gatorback belt as the best. Is there a brand of tensioner that could be considered superior to stock?
Thanks!

Belt chirping can be caused by any of the belt driven components or pulleys. I had one that was caused by the water pump bearings piling up (on my C3) Most are quick to blame the belt when is is just as likely another issue. Good luck.

I already ran the engine without the belt. It’s either the belt or the tensioner pulley at this point.

I used genuine AC Delco tensioner & pulley from Rockauto. They list two grades and I always choose professional grade. I also used the Gator belt, absolute silence from the engine bay as far as chirps

I went with a mechanical Katech tensioner, after seeing every brand, including a GM unit, being built in Korea. Idlers I went with Dayco, being made in America. The belt I chose was a Gates Racing Blue, which I believe is no longer available, which is too bad, as it is the best belt I've ever used. (I used to sell Goodyear/Continental).
