So, after discussing with a Professor of our Department with a very good knowledge on the issue, he basically was in the line of "...JIT design decisions that a tracing JIT encourages versus the default design of a method JIT...", but to be more specific on the advantages he claimed that: "tracing JITs can discover optimization opportunities in common dynamic execution paths that are not apparent to a static compiler or a method-based JIT compiler".
I think this is a nice comment overall, that the PyPy publications and the features they describe can back up nicely.
