Bosch O2 sensor difference

I had so much problems getting my rebuilt 1996 EFI 460 to run as perafr specs ,,,,,it tries very hard to run a little rich even when warm
changed O2 sensor twice ,,,,now I have a Bosch 15717 on it runs ok but at about 13,5/1 afr ......

the Bosch site says that either Bosch : 15716, 15717,15719 would do for my application ....no way to reach tech support ...

anyone knows if there is a different reading from one to the other , like would one give leaner mixture ? why 3 different numbers ?
thanks
Dan

Bosch for years was one of the best brands in the business....now for the past few years I avoid like the plague.....QA control is terrible...and I don't care if you are looking at their dishwashers or O2 sensors..... IMHO
