Nice to see a fresh coat of paint, the old Chrome was starting to look a bit stale compared to the latest versions of other browsers. Love all the new subtle animations and shadows they've added, feels much more 2018 and in line with other Materialised Google products.
If I had to criticise, Google are really going hard on the border radii! I get the circular buttons and new tab bar, but the address bar looks odd to me, especially as it becomes square when you start typing in it - this could have been a slick transition if they'd tone it all down a bit.
I say this knowing I'll open an older version of Chrome in a few months and find it hard to believe we used to live in a world of square corners and gradients.
