I've found that the Windows Classic theme allows you to fit more stuff in the same space. For example, my Firefox bookmark menu fits on screen with Classic with room to spare, where as with Windows 7 and Windows 7 Basic they go piling off the bottom of the screen and I have to scroll around.
There's no need to waste screen space like this!
I had a go with Windows 7 32 bit last night. Most interesting things to note were that third party menus like the nvidia control panel and steam were snappier (they are dog slow on my 64 bit install, Steam often hangs for 20 or 30 seconds), and that while doing the same things it used about 200 MB less memory (sometime more sometimes less). Also, CPU limited game benchmarks were a couple of percent faster.
So, in short, the 32 bit version was a bit faster and used noticeably less memory. I'll be sticking with 64 though, because I want to used all the 64 bits.
