Yeah, Whedon was just there to execute a brief and pick up a paycheck. It was in no sense "his" movie.
I do honestly think Snyder's version will be better since at least it will (presumably) have more tonal and thematic coherence. That doesn't mean I think it will be "good". For it to be good, Snyder would have to suddenly become a good filmmaker, and I'm sorry, but he's just not. At least not when it comes to comic book adaptations.
See, the core problem isn't the style, or whether or not the villain looks like an angry cutlery draw, it's a fundamental lack of understanding when it comes to what makes these characters who and what they are. Same thing happened with 'Watchmen' (which I liked, despite it's shortcomings); he was good at conveying the visuals of how these characters should look, how to shoot and frame them at rest and in action scenes. All of that was well done.
Where it all falls flat is in the character. Batman is not an unthinking, bigoted thug...at least when anyone not named Frank Miller is writing him. Superman is not some Ayn Rand poser boy, perpetually angsty at how much a burden it is to be so great. Johnathon Kent does not raise his son to prioritise his personal convenience above other people's lives, and Martha Kent would never utter the words "you don't owe the world a damn thing". And Wonder Woman sure as hell does not give up on humanity. Ever.
These aren't superficial creative choices, subject to interpretation; they're fundamental traits. What makes Superman Superman is precisely that he's intrinsically selfless. In his right mind, it would never occur to him that saving people is burdensome, in any way. Nor would he feel that the world owes him anything. Quite the opposite. If he didn't think that way then he would be little different from Zod.
What makes Wonder Woman Wonder Woman is her unswerving faith in the goodness of people and her belief in justice and peace.
What makes Batman Batman is his intellect and more critically, his empathy.
