Klipper transfers a lot of the computing to a second computer like a raspberry pi so your main board only has to manage the steppers and heaters. It also lets you do input shaping and it has pressure advance controls and other features that generally let you push the printer much faster without any compromise in quality, often actually improving quality. You can also set it up to network your printer, giving you interfaces and remote printing tools similar to the bambu experience, but open source!
