Grundig Digta CordEx vs. Philips SpeechMike Air

I have worked extensively with the Philips SpeechMike but lately have heard a great deal about the Digta CordEX.  Which device do you think the best overall?

I find them about the same as far as audio clarity is concerned.  I think the SpeechMike is a tad easier to set up, and I think the Grundig is too long:  the controls are harder to reach without moving your hand up and down the microphone.  Still, I don't want to slam it because I do think it's an excellent wireless mic, and maybe someone with larger hands wouldn't have the problem that I do.
