Cohesion 3D vs OMtech K40 upgrade board (smoothie board)

I’m considering which board to buy for my new K40 as I want to use light burn and would like to have the ability to plug in a rotary table as well. I will have a old intel core duo PC for the K40 to serve up the data files to the board dedicated to the laser.

I’m curious what the improvements / differences would be compared between the two options?

Does anybody have input on this? Just trying to understand what some of the differences might be. You can add the LCD with rotary knob for control to the Cohesion board, I don’t think that’s possible on the OM smoothie board any other differences / benefits?
