I own a landscape maintenance company and in my experience honda engines have lasted me longer.
but both are residental design engine with expected use of 2-5 hours weekly vs commerical mower which runs 40 hours weekly
although, price difference 200-400residental and 800-1000commerical
also, if you plan to mulch with it then there is extra resistance and more wear and tear
plan and simple....
you get what you pay for
