please provide insights or what do you think about this statement regards to imploed contract and quasi contract. thank you

An implied contract and quasi contract can be harder to enforce because it is an unwritten contract in these contracts usually both parties agree to terms before performance. While it is harder to prove a case in court if no goods are exchanged but if goods are exchanged like a plumber fixing youre sink and the plumber shows proof of his work then his case will be much easier to win. Smaller companies may often do business with implied contracts.

Like an implied contract quasi contracts are to unwritten but are court ordered preventative measures to ensure that one party is unjustly enriched. However, in a case of work being performed on a house with the homeowners knowledge because the homeowner doesnt stop the plumber then there is no mutual agreement but he must still pay for goods rendered.
