I like how it looks. It's nice to have a fairly-minor shake-up in the aesthetics every now and then, and it makes everything feel a bit fresh and new. And I do sincerely find it fairly minor -- things got a bit rounder and glossier, and there's a few bits of iOS that have some fairly cute glass-distortion effects, and some apps got some not-huge UI redesigns.

Overall, particularly on my phone, it's just giving me an occasional pleasant burst of "ooh, shiny". On my laptop, I admittedly barely notice anything has changed.

(I don't personally have any legibility issues with it, though I'm willing to believe that's down to individual usage patterns.)

1) Aesthetically, I think it's pretty. That's a subjective opinion, though.

2) I vastly prefer it displaying buttons as buttons, instead of as just undifferentiated text on a screen. In the past I've sometimes been frustrated that an app didn't have a feature I wanted, only to learn that it actually had that feature, hidden behind what I'd assumed was just a text label but was actually a button. This is an enormous freaking improvement.

3) I very much prefer the new UI patterns in other places. For example, when highlighting text on iOS, the old UI gives a horizontally scrolling list of options with arrow keys to rotate through them. The new UI replaces that with a ">" More button that pops up a vertical list of all available actions. Again, this is an enormous freaking improvement.

I like the appearance of Liquid Glass, but that could go either way. I think the actual UI implementation behind the graphics is so much better than before.

I agree with the strategy that Liquid Glass is part of.

They are making the iPadOS the mother platform for developing most things - scale down to iOS, or add a few extra changes for visionOS/macOS. iPadOS is gaining features to bring it closer to parity to macOS to make this delta smaller, and macOS is gradually becoming styled more to match iPadOS so apps look at home if the layout and graphic assets were mostly kept the same.

This started around macOS 11, with some major design changes along with Catalyst and SwiftUI to help developers.

There is something about the font weights or I dunno in the context menus on macOS Tahoe that I really like. Somehow, they feel a lot more readable than they did from Big Sur to Sequoia.

And even if I think they utterly botched the concept and execution, I will always cheer the death of "minimullizm" that destroyed Aqua. I've absolutely loathed how macOS looks since Big Sur.
