I absolutely love it. In fact I wish it was way more than it is. I have HATED the flat UI we have had since iOS 7. I hated it back then, and I never liked it. I got "used to it". I didn't start using an iPhone until I got an iPhone 7 CIRCA 2019-2020. Back when iOS 7 came out I had an HTC, and was able to keep it looking how I wanted. I did not update my iPod Touch to iOS 7.
macOS\iOS 26 brings back some of the character we had with Aqua, which shouldn't have ever left. Some people ignorantly compare liquid glass to Windows Aero, which while the comparison is incorrect, Windows Aero is another thing that shouldn't have ever left. It's like people don't have eyes. This is all a very welcome change, and I genuinely hope Apple doesn't let people bully them into going back to the horrendous flat UI I've been cursed at starring at for almost two decades.
