M2 Nano Upgrade

My K40 Laser has a 6c6879 laser m2 controller. I need to ugrade it to run Lightburn sofware.
There are too many choices out there.

Any recommendations on which controller I should go with?

The two easiest choices are the MiniGerbil from Awesome.tech and the Laserboard from Cohesion3D.com They are both plug and play drop in replacements for the M2Nano board.
