U can use filter-list(eg: for as-path access-list) also along with the above three..

All of them more or less achieves the same thing except for route-maps which gives you more felxibility and can reference a prefix-list, access-list etc and also set attributes

Every method filters using it's own technique. What is important is their sequence, which is reversed for outbound and inbound updates.
On Inbound:
1. Prefix List
2. Filter List
3. Route Map
4. Distribute List
On Outbound:
1. Distribute list
2. Route Map
3. Filter list
4. Prefix List
From the other routing process inside the router:
1. Filter List
2. Distribute List
3. Default Weight
4. Filter-list weight
5. Route maps
Hope this helps.
