You're basically looking at Type 304. There are multiple types of 304 (304A, 304L), and also variations between mills. There is essentially no difference between the same steel labeled as 18/8 from one vendor and 18/10 from another.
I'd also prefer 304 to 925 sterling silver. (or, take the sterling set and sell it and buy an ipad and some stainless)
The big lameness is a shift to 18/0 steel, which is cheap and not more durable than 3-5 years, or 14/0 which is essentially trash.
One of the huge quality differences in flatware sets is the knife -- whether it has a real blade attached to a handle, vs. formed from a single blank. The cutting quality is a lot higher with a separate blade, as even great 304 isn't an awesome cutting steel, and you want to heat treat the blade differently. There's also hollow handles, balance, and overall design.
http://www.sheffield-cutlery.com/store.html is a horrible site but I like their selection and quality.
Product page: "Yanagi Flatware... the essence of Japanese design. Warm and organic, yet minimal and sophisticated, it is made of 18/8 stainless steel." (Product page)
It may look nice but will it last? The stainless steel is graded at 18/8 which means it's more likely to rust than flatware graded at 18/10, not to mention sterling silver.
