I will consider switching away from a tiling wm the day I have enough screen real estate. Until then, I want to use as much screen space as possible on actual window contents. I really could not care less about the aspect ratio of my terminal windows - the applications I use know perfectly well how to deal with resized windows.

I was like you, until I began to use a max 2-3 open per tag/workspace. The clutter ended.
Tiling is useless under Unix environments where virtual desktops are a norm since ~1989. They may worked great under DOS and pre Windows 3.1 where few things are open, not under a powerful multi virtual-display based environment with several terminals running at once.
I do have 2-3 open on most of my workspaces. I have 10 workspaces. It's only just about sufficient.
I've used virtual desktops since my Amiga days in the mid 80's - they are not a replacement for wasting as little of what space is actually visible at any given time.
