I'm fully invested in Apple stuff, but strongly considered some third party options. Thought about an OLED 42", which would be killer for games and video, but apparently not very good for text (work use) and had an auto-dimming feature that couldn't be disabled without voiding the warrantee. Then there was the Cooler Master Tempest which seemed to have good HDR and clear text -- almost ordered it, but both the display & the only apparently seller on Amazon both had questionable user ratings and very few user review overall. Just didn't want to make a $900 mistake.If you're fully invested in Apple hardware, the studio display certainly makes sense, though I do think there are better options available. If you're using non-apple hardware the feature disparity is even larger imo, i.e., third party displayers offer more features for non-apple users.
As much as I'd like HDR and a higher refresh rate, the Studio Display has 5K, the built-in webcam, three handy USB-C ports, great color accuracy, and the clearest text in the biz... more important to me than gaming and media consumption, which I do on my OLED TV anyway. It's for my workstation first and foremost. Just wish Apple would have implemented a little local dimming in the damn thing for that price.
