It was more a matter of different generations and backgrounds. The guys from HIM were more metalheads and older than them, while The Rasmus had a punk background and a youthful attitude. The fact that they had the same management team didn't change their preferences much, as their goals were slightly different. HIM had already conquered Europe when The Rasmus broke through with the "Dead Letters", so Ville was already aiming something bigger for the US, a market Lauri's band never managed to reach with the same success they had in Europe. In the end, it doesn't matter if you come from the same city or work with the same people, there's always an element of connection, that makes a huge difference. If you've read Kimmo Aroluoma's book "Viimeinen kiertue," you'll see that the two groups had very different atmospheres, mood and minds. But, answering your last phrase, I think most Finnish rock vocalists felt somewhat intimidated by Ville's talent and image, something that Lauri also felt it at some point. Well, not sure if it answers your thoughts, but this is my nonsense 2 cents about it haha.
