Do you have the linkI wrote the guide that image is based on and haven't updated it in at least a year, so it's definitely out of date. My original was written right as the v1 ZF Bubba came out, so everything after that isn't really discussed besides the original BBR. I also think there's a decent argument to be had between the ZF and BBR for the 55, each has their tradeoffs and suit a different customer but both of them are pretty solid buys.
