Is there a list of Denso A/F sensor alternatives that have been proven to work? Or has anyone found alternatives to Denso sensors that have been proven to work?

So I tried a number of aftermarket a/f upstream sensors from Amazon: YCT, Mirozo, Germban, and Drive star. They were all advertised to work on a base model RSX with an automatic transmission even though they were labeled as 234-9005 which is for a manual transmission. They all triggered a CEL.
I purchased an Engine Dancer a/f unit labeled 234-9006 and it triggered the CEL
I then came across a Nova parts sales a/f sensor 234-9006 (which is for a base model with automatic trans) on Amazon for $66.70 total. I have driven with it a few days and it seems to be working.
I also purchased a Denso 234-9006 a/f sensor for $176.96 on Amazon and it worked as well. Denso is the Original Equipment
