So let's take the development away from a group with several years of experience and assign it to people with much less experience or none? In what world does that make sense?
I think you are missing the point, it is not about one development team over another, it is about decentralizing development overall. Having multiple viable implementations of the Bitcoin protocol allows the governance mechanism of Bitcoin to function more effectively by giving us more freedom of choice.
Experience is important but it is not the only factor. If the experienced group doesn't have the right goals, then you end up reaching the wrong ones.
This comes down to the same thing actually, what is the 'right goal'? This discussion goes in circles. In any case the Core developers are definitely better than those behind Classic.
Classic and Core have different goals, which one we consider better depends on our personal ideologies. I think that Classic is better since I think they are more willing to scale Bitcoin directly compared to Core.
