I agree that the three styles compliment each other very well. They're similar enough to work together but different enough to add variety. That being said, Janick and Dave have more in common as players, while Adrian offers a very different voice. One of the things I really like about Adrian is how he is constantly evolving as a player. He is completely different to the player who first appeared on 'Killers', having added loads of techniques to his repertoire. More than any other guitarist, he brings melody to his solos, which I think is why his solos tend to stay in your mind more than the other two. The way he's been able to fuse so much Blues playing into a traditional Metal style of playing is incredible. His solo on TWOTW is simply stunning. I find Janick's more chaotic style more forgettable, yet ironically, I think he's a superb song writer and his inclusion in the band injected some much needed energy.
At the same time, Janick's early solos were way more melodic. "Wasting Love" you can sing, as well as "Tattooed Millionaire" and even some off The X Factor". I'd guess it's a choice because of how the band dynamics have been since Adrian rejoined. Someone needs to go crazy, and Adrian's not at it...
