I wouldn't say "better", but different.  libJIT has some advantages (just a 
JIT, arguably better C bindings, more standalone, perhaps less JIT startup 
time, closer to our existing JIT but more cross-platform) and some 
disadvantages (no clang to get some JIT for free, fewer developers).

Ultimately I think the libJIT approach will be better for Parrot than the 
clang approach, though there's no reason we couldn't use only the LLVM JIT 
portion and achieve the same thing.

With that all said, I'd like to see experiments with both approaches.
