Actually that's not true. Prefix-lists can't filter odd/even networks
ACL's can, while matching prefix length.
Prefix-lists are rumored to be friendlier on the CPU though...

I think there's no difference in using Prefix-list and access-list for BGP
filtering. As long as you can match the route, both will be OK.
For me, I prefer prefix-list over access-list because it is built to match
prefixes.
