Not to mention that the question is one about readily available specifications that are not a matter of opinion or user experience nor have they changed recently. If the question was, for instance, "Do you notice a difference in build quality, accuracy, durability, reliability, value etc.?" then, although it has been asked many times, there's an opening for new opinions and varying viewpoints.
Finally, lots of posts get links as answers because the link happens to be more comprehensive than the answers the poster is likely to get in response to his inquiry. It is an informed response to a question so I think that any OP should be pleased at getting concentrated info without having to do the research himself.
Nothing wrong with asking BTW. I see many repeat threads. If I'm no longer interested or have answered enough times IMO then I just move on.
