The best would be one that you have enough room to put your stuff yet also easily access it. A drawer system while containing the items more completely will eventually get old if you always have to open a drawer and lift the item out. A plain flat shelf with an open front will allow you to easily see the items and easily retrieve them and put them back easily. A set of bins for nuts bolts and small items is also a good idea but they should be set up near the work bench area for easy reach while working.
I would also gop with a variety. Some stuff needs covering from paint splatter and other liquids, some stuff is bigger or heavier than other things and some stuff you don't use as often as other stuff.
