Well, WinPOET is an implementation of PPPoE protocol. If your account is PPPoE, you have to have PPPoE software in order to make a DSL connection. WinPoet is simply software to make the PPPoE connection.
I think you might be asking if you should use RASPPPoE vs. WinPoet. Both are implementations of the PPPoE protocol. Most people will likely suggest you use RASPPPoE, with lots of compelling reason. I would suggest you use what the provider gives you until you have a working connection and know what to expect. Then decide which software to use.
There are forums here devoted to
PPPoE and
RASPPPoE. I would suggest you spend some time looking these over, there are a lot of details there.
Good luck.
