Cordless is handy when needed, I bought a 40 volt ryobi weed eater when my 15+ year old 2 stroker finally gave up the ghost . Its worked fantastic for our sized yard , big plus is wife just has to pull 2 levers and it’s running she never could get the 2 stroke started . I still prefer corded for heavy duty jobs , drilling concrete is way easier with my 1/2 inch 10 amp heavy duty dewalt corded drill it’s a beast, or cutting thick walled steel is way faster with my old craftsman 15 amp corded sawzall .
