Well, "better" is relative. Web UIs definitely have the advantage you are mentioning. However, they are also much slower to use, so it is a tradeoff.

I am blind and do rely on accessiblity. But I would choose a TUI over a Web UI every day simply because the web is slow as hell. Feels like running away from a "monster" in a dream. You have rich details, but you are being drowned in unnecessary verbosity and an inherently slow stack of tools working together.

The web might be accessible, but it is barely useable in practice.
