I do agree that the first is easier to read.  The problem in this case,
however, is not goops, but rather the lack of an inc! macro:

(set! obj.x (1+ obj.x))

is still less comfortable to read than:

(inc! (x obj))

Note that in the first example the accessor syntax was changed, while in
the second example an inc! macro was assumed.

Thanks to the modified set!, such an inc! macro should be easy to write.
