Being that the technology used in both radios you've outlined (assuming the EX10 has the Ko Propo 2.4 module), then both are S-FHSS and technologically similar. If the EX-10 is the FM version then there's no question.

The EX10 though has a slower CPU, but unless you've been able to notice it I wouldn't count that against it. The lag probably isn't perceptible.

Lengthy technical article if you are inclined: http://www.rcmodelreviews.com/spreadspectrum01.shtml
