What is better? Leetro 6585, Anywells AWC798C, or RuiDa RDC6442G

I recently purchased a Chinese Laser, and the controller seams so glitchey, seams to work good then run it again and the laser goes a little haywire.

It currently has a Leetro 6585, LaserCut 6.1

Thinking of replacing with either Anywells AWC798C or RuiDa RDC6442G.

What will you be processing with the laser primarily? I've used Leetro card w/ Lasercut 5.3 and it gave me quiet a few untimely 'soft dog' errors. And it happened sometimes at random. I've heard good
things about Ruida's controllers however. A lot more stable and resistant to static interferance.
