I think the design is just about 100X easier for mere mortals { in bogus "effortmeters" ;-) }, but it is absolutely true that some backend languages are more suited than others. It is also true that having real optimizing compilers (in whatever lang) as backends will always result in faster running programs (if data is big enough that amortizing optimizer costs is worth it). {EDIT: i.e. "so, trade-offs, costs, YMMV, etc., etc. }
