Hollowtech II bottom brackets - compatability

I'm in the process of collecting bits to upgrade to Tiagra 4700 10 speed on my road bike.

I was about to buy an RS500 for £19.99 from Amazon (seems to be the going price but other places charge shipping too)

However whilst looking I noticed the SM-BBR60 for £20.27. Which seems to be the Ultegra version for only 28p more. From what I can tell it is compatible with the 4700 stuff and has better bearings and weighs less.

It all seems to good to be true! Would somebody mind confirming that it will be better for the 4700? If so I'll get one ordered.
