I have a Sterling 'Power' neck for my Selmer USA alto.
Back story: many years ago, I cut off the reinforcing ring on the original neck which was a shortening of about 3/16". The horn played flat and I needed to be able to play without jamming the mouthpiece on until it was stopped by the baffle. Over the years I have tried several necks on it without really liking them. Then I got the new Eastern Music neck which did play well on it. Meanwhile, I started wondering if I could use the original neck again so I put a new cork on it and tried it out today. It played okay but intonation was wonky (in years past, I didn't have any kind of tuner except an A chime - now with a tuner on my phone, it's easy to zero in and really see what's going on with a horn). After a few minutes, I put the Eastern Music 'Power' neck on and I instantly realized that this neck is very much better for me on this horn. Checking on the tuner, intonation was much better. It does enable a more 'refined' sound if I want it and has a 'singing' quality that makes me want to play classical. BUT! When I want to rock, it's there.
I guess when I first started using the 'Power' neck in the last couple of years I was thinking that it didn't have the power/guts I need, which is why I was thinking about the original neck, but this actually turned out to be the synthetic reeds I was using. Since I returned to Plasticovers, the horn really came back to life.
ETA: I really would love to play only cane on everything but I need a reed on alto and bari that can sit and stay ready to play. I find that Plasticovers work best for me in that regard while still delivering the cane sound.
