KVM Switch for Macbook Pro User - Which One?

Hoping to get a recommendation…

I have a M1 Max Macbook Pro for Work
I have an M3 Max Macbook Pro for Personal.

I have a 39" LG OLED Widescreen Monitor with HDMI or Displayport 1.4 that I want to be plugged into each laptop. Up to 240Hz.

Currently the monitor is plugged into a Cal Digit TB4 dock and I switch the thunderbolt cable from laptop to laptop when wanting to switch.

What is my best option for KVM Switch?
If I just go the USB-C route - the $340 option
I take it I can get 4K 90Hz? and some charging for the laptops?

If I go the Beefier route - the $620 option

  • What is the difference of using USB-C with this option or the Displayport to USB-C Moshi cables?
  • Does one give more benefit than the other?

Am I missing a different KVM that is not one of these that is recommended?

Any help is appreciated!
