You won't want to hear this, but the stock drivers are OK for some firmwares, but not all. I am not sure what point the stock drivers are "broken" but you may encounter some errors if you use them.
I like Bryan Copeland's drivers, I would encourage you to try them. They are available in Hubitat Package Manager, which makes it real easy to install them, If you haven't tried HPM out, you should. Of course, you can always install the driver standalone (without HPM) if you wish.
