I agree with you the first half of your comment - the move from spinning rust to an SSD is absolutely huge; you have Windows starting in a few seconds, which is a far cry from an HDD.
But the 2nd half of your comment, I disagree with. To me, Windows 10 has the perception of being faster than Windows 7 was with the same hardware - most of my machines have been on Windows 10 for ages, but I actually finally upgraded one of my work laptops just today, and this still holds true for me.
With great support for multiple monitors, great high-DPI support, a better command line, Hyper-V, WSL and more, I actually love Windows 10 - it's a fantastic OS.
