Personally I prefer being able to quickly toggle a dynamic window layout based on my current workflow, and switch back to manual tiling when I specifically need to manually tile.
Currently I use Sway too as it's the most mature tiling compositor on Wayland, but once River WM[0], also based on wlroots, matures more I think I will likely make the switch because I often miss dynamic tiling.

On a side note, I hate how window moving works in Sway/i3. I can hardly ever get windows to move to where I want them to go with keyboard. As a result, I have a bind that enters a 'move' mode that takes the current selected window and moves it to a window that I can select. That, or I just use the mouse to drag the window, which is kinda annoying considering this is a keeb focussed environment.
