Rammer every time for me. We have used both...
Pros for maul... erm, you can use it to hit other things (including people unintentionally - the head of our old maul came flying off a couple of weeks ago missing my head by inches
)? Plus one person might find it easier to use on their own
Pros for rammer - can easily be used by 2 people, easier to start off tall posts, less skill needed (vs required accuracy of maul).
We dont have a rammer (we borrowed one a while back) but I am saving up for one!!!
