I see a lot of comparison against logitech flow. At a first glance this is a copy of that feature, but I feel there's no shame in Apple having done it better.
This is exactly what happened with Tablets. Apple wasn't the first to come out with a commerical tablet, but they are now making the most popular tablet in the industry.
They come by, see what's out there, see an opportunity to make an amazing version out of the thing, and then they do it.
The concept of flow is great. Its execution, however, is not great. I have a logitech mouse and keyboard and when I use it just between my personal macbook pro and work macbook pro alone, it works 10% of the time. You can feel the delay when it switches between computers.
My experience logitech options software has also left me sour about the outlook of the company. I've had the mouse and keyboard combo for 2 years and while it has improved, I've had repeated issues with the mice's gesture suddenly not working, forcing me to kill Logitech Options daemon and restart the hardware just to get it going again.
My sister who has a logitech mice paired with logitech Options and the M1 Macbook Pro had connectivity dropouts recently where it just kept switching between connection loss state and paired state, making the mice unusuable.
3 paragraphs goes to show that the hardware is decent, the concept is great, but the execution is poor. Their K380 keyboard, made of plastic creeks which shows cheap build quality when compared to the Magic Keyboard.
I got so fustrated with the combo that I went back to a Magic Keyboard and Trackpad. This was only possible all thanks to Apple's own implementation with universal control and I've been loving it ever since.
Universal control isn't perfect. Sometimes it doesn't connect for me and I have to sleep my iPad and wake it again to make it work or restart my iPad/Mac, but contrary to Logitech, it works 90% of the time and it is super slick.
I use my iPad Pro as a sketch pad and taking notes and switch between my work mac every day. This implementation is the one I've been waiting for.
