I used to own an SCD-1, and have heard the 777es. They are more similar than different, in terms of sound, so for me it would come down to:
Balanced vs Single ended: SCD-1 has both, 777es only single ended
Aesthetics: IMO SCD-1 is an iconic piece of kit, and the 777es is just okay
Price: used, there's roughly an $800 difference between the two
I would add the caveat that both have notoriously slow disc load times (the main reason I sold the SCD-1). I have a feeling that the SCD-1 will keep it's value better because many consider it a legend.
If the price difference is justified by the above then I would go for SCD-1.
