Same result but you are tied to your wm key bindings for navigation. With tmux you have everywhere same bingings. Even on machine you see for the first time. Lost connection? tmux a - t0 and all panes are restored.
(I also use tiling wm, but not for terminal splitting)
Perhaps that is the difference. I don't float around and use different consoles. I would never enter have my SSH credentials on some machine that isn't my own, so would never get to the point of using an SSH session from a foreign keyboard, screen, and window manager.
My workstation and my laptop computer are my interfaces to the world for 99.9% of my interactions. Without them, I am not working. The only exceptions might be touching a KVM console on a server in our machine room to see diagnostics (otherwise I would use SSH from my office) or a lab computer where I'd only be running local browser or demos.
