BGP filtering in/out: Filter-List vs Prefix-List vs Route-Map

Hoping to get some expert advice regarding BGP filtering:

     neighbor x.x.x.x filter-list<as-path acl 1-500> in/out
     neighbor x.x.x.xprefix-list<prefix name> in/out
     neighbor x.x.x.x route-map<route-map name> in/out

I have become accustom to making route-maps for just about any filtering requirement.

I am wondering if there is a reason to prefer one of these other commands (filter-list or prefix-list), besides the convenience of less steps.   Order-of-operations?  Other considerations?     

Thanks for any clarification or reminders of issues to consider.
