The comparison you are talking about happened back in the 50's and early 60's. It's part of history. Many of us were either kids or not born yet so we read about it today.
Turn back time to 1949. Carter W1 on a Chevrolet 216. Works well and still does today. Then in 1950 GM buys Rochester, gives Carter the boot out the door and Chevrolet begins installing the B/BC because they can save money. The Rochester works okay for a while until problems start showing up after the warranty has expired. Some people remember the old Carter reliability and want it back. Carter's new aftermarket/replacement YF has less trouble and also performs better (advanced metering technology), their mechanic recommends it so they swap out the Rochester. They like the YF. Not everybody does the swap (Chevrolet owners are typically cost conscious and new carburetors are $$$) but many do. Thanks to someone who purchased my YF many years ago, today I have an excellent carburetor on my 1955 engine. Cleaned it, checked for wear, put in a kit and installed. I also have 2 B's that I haven't been able to tame so they are sitting on the shelf.
