Ding Ding Ding we have a winner winner chicken dinner. Are you spraying Chinch Bugs @ 5 gallons per thousand or weeds @ 0.5 gallon per thousand??? Now add in what size pump, Gasoline or 12V. Then comes the big factor of PERSONAL PREFERENCE. Ride on Boom sprayers can be calibrated more actuate but will overlap especially at turns if you are not careful. On 12V spray equipment I like to use Pressure washer guns and Quick change nozzles. Many times I am spot spraying and the 15 degree tip is great for spotting weeds. .
