Can't tell the difference between itead and darkxst firmwares for the sonoff ZBDongle-E model

I have two firmwares, one from itead that is ncp-uart-sw_EZNet7.4.4_V1.0.0.gbl and then another from darkxst named ncp-uart-hw-v7.4.5.0-zbdonglee-115200.gbl

Is the darkxst one supposed to be newer since it has the higher version number? It seems like the one from itead was released the most recently though.

I haven’t been able to tell if one of these is “better” than the other, or what pros and cons each might have.

If anyone can help me out I would be greatful,

Thanks
