it seems like tos Spock was more the stereotype of what people (in the fictional reality) think the vulcans are and how vulcans want to pretend to be, but when you look at the franchise as a whole nuSpock's portrayal does fit with the canon idea of the vulcans, rather than the fanon one, more.
honestly, also, I think it was easier for tos Spock to 'look' as the controlled one at times (which was itself just appearance for him too) when he didn't have to face the challenges nuSpock faces (and even tos Spock was emotional beyond his facade)
really, it's easy to show vulcans being in control when there is nothing really awakening that part of them that actually has strong emotions.
I also think that nutrek is less stuck about characters having definite roles at any cost. In the old thing, Kirk and McCoy were the human and emotional ones so in some way that made it even easier for Spock to pretend to be the controlled logical vulcan of the situation because he compared to them. In the reboot his purpose isn't being just the alien sidekick and this means that we get to see him beyond what the other characters might see of him. He's more a protagonist with Kirk.
