If one of the paths is more than a few lines I would probably opt for
if( can_fast_path )
{
#do fast
}
else
{
#do slow
}
purely because I think it remains more readable to have each in a
block that stays indented and with the if makes it more obvious that
it is either/or and that there is no reason the code should run
anything other than only one of the blocks
