Its real. If someone really likes 3 Under I'd always say to get a bow thats tillered for it for less noise. Can you quiet that super grizzly? Sure. There's a whole list of things to slap on the bow, raise the brace, heavier arrows, etc, and those things will help with split too. I'm biased, but I say if you're starting out and you can do split well, do it. Some guys started 3 under and after many years they just feel weird going split, and vice-versa. But thats just my opinion and there will be a legion of 3 under folks who have zero issues it that should be along shortly.
