Yes, the 5D3 is the most reliable of the bunch by far.
After shooting raw for the better part of last year, I have yet to experience a single corrupted frame.
Tomorrow I'm shooting a narrative short film on two 7D's which we have extensively tested in raw for almost 2 months, once again I don't foresee any issues.
The most important element of shooting raw is to budget for a DIT on your shoot. There is simply no way around it, you will need a person full time on the set whose sole job is to manage, convert, and backup all the incoming footage.
But yes, once and for all, ML is a stable solution for most situations. The exceptions would be docs (where you interview people for sometimes hours), weddings (why add all the extra work for yourself?), and ENG.
Now stop procrastinating and go out there and shoot!
