Seeing a lot of mixed feelings about the AWS UI here. Just my two cents: a good project shouldn't need it for anything much beyond fiddling during development and poking around during problem solving.
In the latter case, I deeply appreciate the minimalism compared to something like GCloud. You can pump the refresh button on many AWS consoles and they refresh in a second or two. Progress spinner cancer while present is minimal compared to many popular platforms, and in particular relatively nonexistent compared to the white elephant that is GCloud
Given the choice between a half-developed AWS console basically emitting some raw XML in a <pre> tag, and the overengineered overdesigned monstrosity of GCloud, I'd always prefer the fast hacky option especially while trying to figure out why something is broken.
While the GCE panels look visually fantastic, there are so many cases that make it obvious actual engineering workflows weren't considered during the design process. Be it missing buttons from the context-sensitive toolbars, pointless sidebars, or screens you can't refresh except by hitting F5 before leaving for lunch. I've yet to see any part of GCE that could be described as "snappy". Plenty of AWS bits come much closer to that (although I notice AWS has started slipping down the GCE road to hell in a couple of their newer service UIs)
AWS is far from perfect, I can't stand CloudWatch, but relatively speaking it is perfection compared to stackdriver
tldr I'm glad it's ugly, it means they were focusing on the important stuff
