The phrase "most lawnlike" can be a bit subjective, but there are several synonyms that could be used to describe a lawn that is well-maintained and attractive. For example, "manicured" suggests a carefully tended appearance, while "tidy" implies a neat and organized look. "Primped" connotes a sense of precise grooming, while "neatly trimmed" emphasizes an orderly and smooth surface. "Pristine" suggests a lawn that is in perfect condition, while "well-groomed" implies a sense of sophistication and attention to detail. Ultimately, the synonym chosen will depend on the specific characteristics of the lawn in question and the overall impression the writer wishes to convey.
