I find their asymmetry to be ugly and visually distracting: there's no excuse for the "chin" on the top of the monitor - I'm surprised Apple OK'd the design at all - and just-as-surprised that they didn't equal-out the bottom bezel of the display in the new 2019 revision just to make it seem balanced.
Also, the fact it's a single-input monitor without HDMI input is a deal-killer for me: multiple-input monitors are fantastic when you have multiple machines on your desk and alternate between them based on the current job (e.g. laptop in docking station, Mac Mini for Safari + iOS testing, main desktop, dangling HDMI cable for connecting to tablets and phones).
