SMS, I'm not sure what you mean by "star safire HD interim". Here are the differences I have noted from personal experience of the Cineflex and product information for the others. Once again I stand to be corrected if anybody has better information:-
STABILIZATION SYSTEM
Cineflex V14 MS2 - 5 Axis HD, 4 Axis IR

Wescam MX-15i HD - 94

In all other areas that I've been able to ascertain so far it seems they are pretty similar, but the big subjective issue on which most people comment is image stability and the only way to do that is by head to head visual comparison. I'm happy to post a couple of Cineflex examples if anybody can reciprocate with the alternatives?
Not sure if that answers your question?
