Devo 12E vs Devo 10 white

Hi,

Could not find any reviews of Devo 12E... It is not clear what are the differences between Devo 12E vs Devo 10 white.
Is it just extra 2 channels or there are other compatibility/power/software issues to look into?

Also would be great if anyone could recommend a compatible 6+ ch receiver to pair with either of these transmitters.

Thank you,
Michael
