Haven’t done the ranking, as I kind of find that pointless; what matters to me is:
1. How long do I have to wait for the boot process to complete so I can do what I want to do?
2. How responsive is my machine, compared to Visa or XP?
3. How stable is the new OS?
In my experience, with my HP laptop; it boots faster than Vista by a long shot. The machine appears to scream, I mean I’m clicking on IE8 and surfing the net faster than my Quad Core XP machine can even open IE8.
It’s never crashed .... ever.
The downside is that for reasons unknown, I could not upgrade from Vista to Win7. However, every file was backed up in a folder on the desktop - just copy the files I needed, and re-install my applications. Pain in the butt; but it worked without issue. For reasons I do not understand, Win7 is far ‘faster’ than Vista on my laptop.
The ONLY reason I have not upgraded by Quad-core (Core 2 Duo) boxes is because there are no supported drivers for my Dell laserprinter. I just can’t justify the improvements in performance in my 2 PC’s against trashing a perfectly functional Dell laserprinter.
