I don't have golden ears, but...
I bought the KRK Rokits, and I A/Bd them against the Event 20/20s. Here's why: The Rokits held their own, and they're a lot smaller. And I don't have much room for big monitors. That's it.
The comparison was done in Guitar Center--not the best place--with Steely Dan's Aja for about an hour at different volumes and distances. I felt the 20/20s had a little more detail and produced a little better stereo field. The 20/20s seemed to accent the lows and highs a little more, and the Rokits accented the mids a little more--no extremes either way. Overall, I rated both excellent.
Bottom line for me: The Rokits fit my space perfectly and sound great. I drive them with a Hafler TA 1600 that seems to be a perfect fit. Although, if I had a bigger space for my monitor setup I would have bought the 20/20s. I don't think you can go wrong either way.
I must stress the Rokits held their own. They are very well constructed with high quality drivers.
I don't think KRK makes any junk.
