I personally feel Expose hit a peak in functionality with 10.5, went downhill with the forced grid and gaudy glowing blue, became useless and slow around Lion or so, and is now finally about back to where it was with Mojave. 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.
