I've used an Electro quite a bit, and yes, you can SORT of get used to the buttons, but there are a lot of things you used to be able to do with the drawbars that are difficult to pull off with the same precision that 'shading' the drawbars can do.
I feel that Nord typically appeal to those that didn't grow up playing with drawbars, if the truth be told...
To be honest, being able to see what the presets are is no biggie. On a B, those reversed keys brought up the presets, and nobody whined about not seeing the results on the drawbars! You HEARD what they were.
Truth is, it is CHEAPER for the button system, not necessarily better...
As I said above, if someone came out with a drawbar controller for $200-300, you'd quickly see how many people disagree with Nord's direction!
