to add my opinion:

the reason that the duets are so expensive is the fact that they are essentially selling software and hardware together. modular is good, but when something starts off using the best, things tend not to break and upgrades don't make much sense.

i do like the SKR boards (despite never setting them up), and IMO they are perfect for "normal" printers, but as soon as toolchangers, water, second x/y axis, thermocouples, etc are introduced the amount of modification to them vs the duet make the duet the clear winner.

in my opinion, the skr and similar boards are the best choice (as everyone else here has said) due to the fact that a fully kitted out controller costs ~$150usd, while the duet costs ~$400+ fully kitted out. the duet is IMO indisputably the best controller one can buy, but for the average printer the extra cost isn't justified.
