That depends on what you need:
100+ Thunderbolt 4 / USB4 Docks & Hubs compared (updated 2023/01/30)
I personally have this dock:
Satechi often has 20% off sales making the dock $240. They have a 15% off coupon that works nearly all the time IPADOS, which makes the dock $255.
The dock charges the host at 96W PD.
The dock's ethernet adapter is based on Realtek RTL8153. It causes high CPU usage as macOS does not have a good driver for it. You're better off buying a USB-A 2.5G ethernet adapter based on Realtek RTL8156 like this one to hook into the back of the dock:
Alxum 2.5 Gigabit Ethernet Adapter
The audio jack has a lot of hiss. I would avoid using it with low impedance headphones. Either buy an impedance adapter or use a USB soundcard. I use a cheap USB-A soundcard:
Creative Labs Sound Blaster Play! 3 External USB Sound Adapter for Windows and Mac
The dock has three downstream TB4 ports. You can use two of them to run two 4K@60Hz monitors via USB-C to DP or USB-C to HDMI cables. This cable is VESA certified and supports HDCP 2.2 for playing DRM'd Netflix 4K:
Maxonar USB C to DisplayPort 1.4 VESA Certified
If you have $400 the CalDigit TS4 is highly reviewed:
These are the soundcard and microphone I am currently using.

Or, if you care about audio quality, spend $20 on a USB DAC instead.
1000 X better than those tone sucking thing you just talked about.
There's plenty of USB DACs for $100 or less ..... they will offer better sound quality than the on-board audio on even the best motherboards, true Hi Res Audio, and all you give up is a USB port.
