Basket is better if you do not fold the bike ever, or if you plan on carrying bigger or odd shaped items.

Most Soft Panniers will not intefere with folding the bike. and makes it eaiser to fit in the trunk or hatch of a car.

Finally Cheap 3rd party Panniers can be good. almost all 3rd party baskets are.... not so good.

and compared $170 for the entire Lectric cargo set. or even just 1 basket at $60 vs... I got my Roswheel bags for $40 even.for my 2.0 ST. thats 3 bags.
