Quote from a klipper's benefits page I found [1] "Klipper uses the extra computing power and built-in algorithms to better calculate step movement times for motor actions, achieving movement precision of 25 microseconds or lower. Scheduling movements with an external computer also allows your machine to can carry out more actions in a given period."

It ends up meaning quicker, better quality prints. Input shaping and resonance compensation make a world of difference when printing quickly.

I also have a bltouch on my ender3; I found the bed leveling procedure with the bltouch to be way easier and more precise with Klipper.
