When it comes to preferences, I fully agree with you. Only Dylan/Ellie I would mention here additionally.
As for Sophia being a more active character, however, I'm a little skeptical. Not because I don't think that a more active Sophia would have been fun, but more because in AWAM Sophia is almost the only character that really needs to be corrupted. If she then virtually switches roles, there would be almost no need for any corruption any more, with the exception of the only alternative is Dylan/Ellie.
I think your assessment here is fundamentally wrong. I suspect that there are not much (if at all) people here who find only Dylan content in AWAM interesting. This problem of not liking a major story charcater is something you have, but for many here applies only to minor side charters, if at all. I think that most of the people who chose Dylan on there Vote also have Ellie and even Sam on their list.
For example, Even though I find the content around Sophia/Dylan, Sophia/Ellie and Dylan/Ellie in AWAM the best, I will certainly watch the other paths as well.
