There are ups and downs to both. I prefer to have a choice if given a choice. And having the freedom of choice is always hard. But there’s a lot out there if all you want a limited UI as well.
What is _really _needed is an easier way to program the UI - via smartphone app, Bluetooth, USB, whatever. Hitting a button 2000 times to get to a config menu, then another 600 times to get to a specific setting, etc., etc., is not my idea of fun, though I understand it’s the best that can be done with one button. Even having to take a driver out of a pill to flash it can be a pain for a noob. Heck, I find it a pain. On larger lights where there’s more real estate on the driver how about a half-pitch micro DIP switch? A nice 40 cent part to make life easier?
