Worth pointing out that it's not just the Smoothie that has more user-friendly configuration, better step pulse timing, more precise acceleration etc. because RepRapFirmware on Duet electronics does all that too. AFAIK it's also the only firmware that calculates the step pulse times on a delta properly. All other firmwares that I know of (including Marlin and Smoothie) chop up moves into shoit segments, and then assume that a short linear move can be approximated by linear moves of the motors.
The only remaining reason to use 8-bit electronics and firmware is if you are working on a very tight budget. But 32-bit processors are inexpensive now, so the price of 32-bit boards should fall.
