The only differences are that if you type into that view, it searches Spotlight-style and off the right side there's an auto-hiding multi-desktop switcher. Both are tastefully descreet and strictly improvements imo.
Exposé was a feature of a time when Mac OSX was at its peak. The OSX usability guidelines were very different to the Windows ones, and it showed (every user coming to Mac had to adapt). Apple decided to throw all this away a few years ago. Exposé was turned into Mission Control, which has more features, but worse usability and aesthetics. And macOS is more intuitive to Windows-trained users, at the expense of consistency and power-user productivity.
In the interim I started using Hyperdock which brings windows 7 style window previews to the Dock and I feel like it scales better to large numbers of windows than anything official from Apple.
