Braycote has enough nice properties that it is also (often) the lubricant of choice for a lot of space applications - which in many cases justify its (ahem) astronomical price. Its low out-gassing in vacuum and lack of mobility are huge assets there. I have not personally used it in any terrestrial applications, nor are any of my machines pricey enough to warrant it, so I can’t advocate one way or the other for its use on a classic computer.
