OK, so which is the best? the one from the website or the one in
stores...which is more realistic

I think there's a bit of misunderstanding here.

X-Plane is updated by the author quite often. But you get the first release
(currently, release 8.00) on the DVD.

Then, after you have installed X-Plane 8.00 from the DVD, you can simply
download the latest release (8.40 at this moment) from the website
www.x-plane.com, and update it.

Obviously, later releases have always some improvements in realism and other
feautres over previous ones.
