Less tendentiously, write/small-fast.

I assume that the first one writes datum labels for cycles but not
for shared structure?  That would seem to violate the whole notion of
read-write equivalence: you write out a value with shared structure as
a datum, but you read it back as a value without shared structure.

You can also do this by manipulating imports.  In the default Chibi
library (scheme), which is not R7RS-compatible, `write` is the /small-fast
variety; in the (scheme write) library, it's the /shared variety.
