Putting my work hat on for a second, I would prefer a known correct and stable implementation that works on many platforms without change to one that was 50% (say) faster. However, this is because I'm working with data that has a very very long lifetime, and so I expect any code to be used on a range of platforms over the lifetime of the software. Other people of course will reasonably have divergent views.
