Nah...
The Dock in macOS is a very different animal, compared to the Dock in iOS. The size of both the Dock, and the icons in the Dock are dynamic. The macOS Dock is continually modified with more icons as you open other apps.
Some folks use a Dock with only minimal icons, or don't ever use the Dock, leaving it hidden at all times.
Some folks put the Dock on the side (I leave it on the right, and never use the bottom position), and having the dock available at all times, without needing to go to the home screen, then, of course, using the dock icons as drop points for files, either the copy files to folders, or to launch applications simply by dropping files on the dock icon - etc, etc, etc.
All part of the macOS experience, which is different in many ways from iOS.
I can easily extend the Dock to cover the edge of the screen, but I use the non-Dock areas in the corners for other purposes, such as dragging windows or files to those positions for easy retrieval. Yes, I know there are other ways to do this, but it is a part of my workflow. Can't do the same things on iOS. Hot Corners don't work the same with a fully extended Dock.
Bottom line - it's macOS, and the floating Dock is better.
But, to answer your question - I like the "look" of the full width Dock, but I won't ever use it that way if I have the choice, and it's not related to how it looks. It's the usability when floating (for me!)
