I would agree that you should just shoot it, and not get caught up in any name-worship.
That said, Kodachrome IS unlike any other film. Like anything else, it has a 'look' and its look is particularly unique.
I've got 4 rolls left and am well aware the clock is ticking. I had great luck shooting my stock last year while on a trip - lots of street stuff, interestingly, so don't worry about slow speed.
