Well, probably you cannot really compare these two.

Ravenscar ist just a profile on what Ada features to use and what not to 
use. In this sense the concept (subset of existing language) might be 
seen similar to SPARK. But SPARK is a Ada-subset language with 
additional annotations for automatic proof and in some terms it is far 
more restricted than plain Ravenscar.

So, from what I know, I'd say most if not all SPARK programs would 
conform to Ravenscar, but a Ravenscar conforming program is not 
necessarily written in SPARK.

So, in this view SPARK programs look safer, yes. ;)
