If you set Liquid Glass to the more opaque mode in settings I find iOS usability to be fine now, and some non-flashy changes such as moving search bars to the bottom are good UX improvements.
The real stinker with Liquid Glass has been macOS. You get a half-baked version of the design that barely even looks good and hurts usability.
iOS 26 is a disaster on devices with 4GB RAM though, so I'm not upgrading my iPhone 13 Mini again (that was a traumatic few days).
Still takes multiple taps to find something on a page in Safari.
