I own a lot of hex keys, they're one of my most used tools.
Current favorite is Eight Tools. Their taper head hey keys are some of the best I've ever used in terms of fitment (especially the ball end): https://www.eight-tool.co.jp/en/tapaer-head
I also really like Wera Hex Plus and they've served me well for a long time. I buy the ones without the plastic sleeve, those sleeves always come off eventually.
