Bold is bold. Strong is Strong. One is visual the other semantic... at least that's what I got out of all this wunderbar of doing the same thing two different ways. I read it as markup for accessibility and some pissing contests between the spec writers. Haven't changed my ways <b> does exactly what I want it to do for a visual person and in most cases I don't want my text shouting at a visually impaired visitor. That would be RUDE! :)
And if I got it wrong, no worries. Either way I seriously doubt that b will be completely ignored... too many sites, too many lagging tech, too much web and... if it ain't broke, don't fix it.
But as far as SEO is concerned I haven't met a bot yet that parses TAGS/ELEMENTS for serp returns... they want the CONTENT.
