Which one is better


which one is better the mks gen 1.4 or the mks gen l board?
I have a tevo tornado with I think a bad driver
and of course it has a mks 1.4 base board


I ordered 2x MKS gen1.4 for my printers
both have different revisions. But decent Mosfet and connector for which i have connected to my boards.
But i resoldered some connectors because they were lose.
