Is Klipper worth it on the Aquila 1? How much faster are we actually talking?

Been running stock Marlin on my Aquila for a while and seriously considering flashing Klipper. Main draw for me is the speed gains from Input Shaping — curious what kind of real-world improvement people are seeing.

Are you guys actually printing 2-3x faster without quality loss, or is that overhyped? And is the Raspberry Pi setup as painful as it looks?

Would love to hear from people who’ve made the jump — was it worth it?
