If you have the choice of pppoa vs pppoe why not use a so you can use
overhead 10 and be more efficient for upload.
For the record - choosing PPPoE usually allows switching [very cheap]
adsl routers into bridge mode - avoiding their connection tracking
limits altogether (great for torrents) and getting public ip on linux
machine easily.
