I bought this flash a few months ago and am very glad I chose it. I'm not a pro and I still have a lot to learn about flash photography, but I've found it works well for most of my jobs. I love how easy it is to program the flash output (1/1 to 1/64) and the guide number is impressive (61m/200ft), although I think it's a bit more than that, what you actually get (I've heard that same goes for all other breakouts). I am also impressed by the advanced features of this flash such as TTL wireless, high speed flash and second curtain sync. You can also use manual flash mode if you want to dial in an aperture that tells you how far away you want the subject to be. My only criticism of the flash is that it's a little hard to see in manual mode (and the user manual) and the letters on the LED display are pretty small, although they're backlit, which is nice. All in all, I really like this flash!
