Eh, it's all about personal preference. I like simplicity, so to me Windows 8.1 looks great. Simple clean lines that make it very easy to see what's happening on screen. To me it looks a lot better than Vista/Win7 Aero themes with their semi-transparent windows. I really struggle to understand why people like Aero "bloat". Back around the time when Vista came out and everyone marveled over the fading minimizing windows, you'd see a bunch of youtube videos showing off fancy visual effects on linux such as cube desktops. Linux guys would point to them and say, hey we've had this for years, YEARS I TELL YOU, linux forevah! And I always found it funny because the first thing I would always do on a clean Vista install was disable all those fancy video effects because I was just too impatient to wait half a second before the window minimized. I had a fast computer at the time and I expected immideate response to my action, I did not want some artificial delay inserted between the time when I clicked minimize and when it actually minimized. That was just stupid. Same with Aero styles. The flat Windows 8 style is easier to navigate, it's easier to see which window has the focus. Some may like the Aero "bloat", well fine, but that's a personal preference of style over function. The flat style is no uglier than semi-transparent aero, but I'd argue it is more functional. Anyway, it's all personal preference.
