Since I have owned both a first gen and currently own a second gen Edge, I have had HIDs in both.
In my first gen, I had 6K HIDs in in both high and low beams (Necessary for driving in certain parts of AZ). Lived with the blue and jagged pattern but that did not outweigh my light output. In the second gen, I went down to 5K and enjoy the light output from that. As others have said, you see the blue but it's not in a critical viewing spot.
