Is the Keil-output code consistently smaller?
Yes
Does it consistently run faster?
Yes
Is it more reliable?
Yes

Is it more expensive ?
YES

Can I hack it at my will?
NO

(and, at least the "more expensive" may turn out to be the other way round in specific cases)

PS. I know of at least two "hacks" made to support specific derivatives, AFAIK supported by the respective chipmakers: the Dallas' 390/400 which made it to the "official" variants of SDCC; and the Infineon's XC8xx, which is unfortunately not "official", ergo is bound to a specific - and rather old - version of SDCC.
