"Shaped Beam" lights like the Saferide are absolutely fantastic! For the reasons you mentioned - puts out light evenly, doesn't wreck you night visible, and is visible to other but doesn't blind them.
Want to point out that I think the Ixon IQ
Premium is even better, though.

The Saferides biggest drawback is coming with crappy batteries, and poor battery life. There was a trend of the stock batteries it comes with being defective, and even if they weren't runtime only seemed to be around 1 hour. Put better batteries in it (like Enelopp XX's) and it was less than 2 hours. The IQ Premium is 4-5 hours.
From online pics, it looks like the Ixon IQ beam pattern is wider, more even (as in less artifacts), and puts more light closer to the bike (convenient though not required), but I since I don't own a Saferide to try side by side I can't be 100% certain.
If the battery life isn't a problem for you, the Saferide otherwise sounded like a decent light. :-)
