Shimano SG-8R25 vs. SG-8R20?

If you recognize the model numbers, you probably can answer me: what are the actual, real-life advantages of the SG-8R25 compared to the cheaper SG-8R20 (beyond the marketing speak by Shimano)?

If you posted Nexus 8 vs Nexus 8 Premium, you might get some more feedback.

I have never had feedback from Shimano itself, but on the Breezer bikes website you can read this:
Quote:
It is 200 grams (nearly 1/2 pound) lighter than the Standard Nexus Inter-8, and is easily distinguished from the standard 8-speed by a RED BAND on the drive side of the hub barrel.

Additional needle bearings offer greater efficiency and durability over Standard 8 and 7-speed hubs.
Basically, they are more robust (better life expectancy if you carry loads and ride a lot of hills), lighter (tho 200 grams is not that much, but that depends what kind of rider you are), and should shift better.

The standard Nexus 8 hub is best suited for cruiser and comfort bike applications. The Premium version is ideal for heavier applications like a daily commuter or messenger/commercial use.

8R25 is still available. That`s a pretty good advantage in my book.
