personally, i consider ^5 and ^6 sorta interchangeable as "mid range"since they are fairly close together temperature-wise. I guess it'd really comes down to how your clay acts at the hotter temp as well as the needs of your particular glaze. It's fairly common for a kiln to fire hotter on top since heat rises, and it can be as much as a cone's difference depending on how the kiln fires. I'd also assume a commercial clay is formulated to be slightly forgiving in terms of 1-2 cone difference - but then again some clays will slump at the temp indicated on the label, it all depends. You're also not specifically limited to a ^5-6 clay - lots of people who fire to mid-range still use stoneware clay body (depending on what you're doing of course!). Same goes for glaze - some work great at either cone, just depends on the glaze.
