Sorry can't give you any advice on the Cardo Scala's as I have never used them.
There are 2 different kits for the SMH5's, one has boom mic with foam noise cancelling covering on it for an open face (3/4) helmet which is what I use. I have talked on the phone at 50 mph and people say they don't even know I am on a moving motorcycle. The other kit has a mic that fits into the chin bar part of the full face helmet.
I use a couple different helmets so for an extra $35 I got a second set of the earphones, mic, and helmet mount. I just pop the transceiver part of the system on which ever helmet suites my fancy that day. Blu-tooth on them has worked great with both my iPhone and a TomTom Rider GPS. Use my iPhone for music and while not top quality audio it works.
Communication is great between rider and passenger. I have not tried bike to bike communications yet.
