There are pros and cons to every option out there - and everyone has their favorite or the option that they would "never use" --- ultimately, it's going to be a matter of trial and error to find which works best for you, your management style and your birds.
*I* use deep litter method (DLM) using pine shavings on the coop floor - and a poop board lined with PDZ. In the past (the flocks I kept when I was growing up) we bedded the coop with straw and I much prefer the shavings over that. I am not fan of smaller particle stuff (ie sawdust) as I like having a lot of air movement through the coop in the summer and smaller/lighter particles get picked up too much in that, the shavings are large/heavy enough they don't blow around.
Things to consider in your own pro/con list:
what size is your coop/will it be --- does it allow you to enter into the coop and stand up/move about or is it designed in a way that you will have to reach in to clean? how heavily stocked is the coop going to be? How much time, daily, do you plan to give to coop maintenance?
