Can't tell you the "best" smart cover combo. There are lots of options and almost as many opinions. I can, however, suggest one to avoid. Purchased the "genuine leather" back cover from Bear Motion on a "one day sale" through Amazon for the ridiculous price of $2.99 and free shipping. (See url below.)
No, I'm not that naive. I was skeptical that it was "genuine leather." But since it was supposedly a one-day sale with a claimed retail price of $50, I thought I might get lucky. And since I was ordering other items from Amazon, I tossed it into the cart.
Not "genuine leather." In fact, the box label (unlike the Amazon description) indicated it was "real non-leather," whatever that is. Cheap pebble grain "leatherlyke" fabric glued to a plastic back case. An interior "fleece-like" fabric that was equally cheap and apparently cut with a dull knife.
Not a "one day sale," either. More like the oriental carpet stores that are continuously "going out of business." The "one day sale" is still going on.
But the worst part was that it simply does not fit. Period. The crimped and glued leatherlyke cover wrapped around the corners and was so incompetently attached and crimped into a bulging mess that the iPad could not be completely inserted into the cover.
Frankly, I would not have ordered this piece of junk if I hadn't read positive reviews of Bear Motion's other (more expensive) products. I won't make that mistake again.
Despite the measly amount involved, this one is going back to Amazon on principle. And for the umpteenth time in my life, the old sayings that you get what you pay for and that if a deal seems to be too good to be true it probably is turn out to be good advice.

P.S. On the brighter side, I have clear back covers from Speck and from ENKI.
The Speck model has a metal strip on the back that holds the SmartCover in place when folded over. Very nice touch. However, I found the strip itself came off after about a month and had to be re-glued. Not a big deal but disappointing. In addition, the cover itself (quite light and thin) tended to pick up lots of scratches. Better than the iPad being scratched but after a couple of months it was looking rather drab.
The ENKI (
www.enkigear.com) is another long story. Pre-ordered one and put up with the company's fiasco of late shipping and low quality (sharp edges and no mic hole.) Bought it partly because of the price (included a sleeve and screen protector for $30) and partly because it's manufactured in the USA by a small company in Michigan where the economy is in rough shape. Eventually received an unsolicited replacement case with an improved design and better quality. It's an excellent case. A bit thicker than the Speck and much tougher. Perfect fit.
Not sure I can recommend ENKI given their early problems but they now have an expanded line of SmartCover color-coordinated back cases. And the redesigned model is, as noted above, very high quality. They seem to have overcome their initial problems (from what I can tell on their facebook page.) So if you're willing to take a chance, their cover may be worth considering.
Edit: Since writing the review above I've been contacted by Bear Motion and have been assured that the case in question is, in fact, genuine leather. The label on the box stating otherwise is a coincidence stemming from the contraction of the word "companion" to "nion." This doesn't change my opinion of the product or the fact that the version I received will not fit my iPad. But I feel it's only fair to revise my earlier comments regarding whether it is or is not genuine leather.
And still another Edit: I don't usually do this but written such a negative review I feel obligated to mention that Bear Motion has sent me a replacement case to try and a pre-paid return shipping label for the faulty case.
The reason I mention this is that Bear Motion has demonstrated an incredibly high level of customer service, especially considering that the product in question was a measly $2.99. I have no idea if I'll be satisfied with the replacement but I have to say that the customer service and concern demonstrated by Bear Motion (over a weekend, no less) is impressive enough to bear noting.
