I've got burnt pepper, blushbaby and mocha. Blushbaby is the shade I've been using the most, as it looks like a natural flush of colour on me and goes with many different makeup looks, anytime of the year. For a sheer blush I find it to be very pigmented, but I don't mind. Mocha though is a different one. It actually is sheer and needs to be built up. It looks a lot like blushbaby, although a different tone, but I prefer blushbaby to mocha, which means that I haven't used it as much so it's just laying there. Perhaps I ought to give it another chance. Then we have burnt pepper. It's a lovely and verrrry pigmented shade, so I just let the bristles of the brush barely touch it. Trust me when I say that that's enough to get that lovely, red flush on the cheeks. I think it's great for summer (especially if you've got a tan or wearing bronzer), and autumn, but if you want to use it all year round, then go right ahead. That's the wonderful thing about makeup: There are no rules. You do you. Lastly, I would like to add that since many of us don't wear makeup every day, there's a lot of product left by the time it expires, which means that you have to throw it away. That's neither environmental friendly nor bank account friendly (the latter part maybe not so much for MAC). Therefore I suggest a mini version of your blushes, like your lipsticks, which is good for when you're unsure of the shade, or if you're like me and don't wear makeup every day.
