I like chicken breast at 140/145 because I love that texture and juiciness. If you want it to shred like a more traditionally cooked breast then you can cook it at higher temp. If I’m doing chicken for tacos I’ll up the temp a bit.
But then I love chicken sashimi in Japan as well.
Same with pork. I don’t LIKE it cooked all the way through unless it’s stewed.
A scallop sears and is done, in a hot pan, in a minute or two. So there’s no benefit to SV.
OTOH lobster poached in herbed butter in the bag at low temp is, again, a texture you don’t get other ways.
Natirally some people would rather the texture of a boiled lobster. Not me.
