I find ADDS the most useful. I also use DUATS because I need a legal

Legal? Maybe you mean that you think there is an audit trail, so if necessary
you could prove that you actually got a briefing. I think that too, but I'm not
sure why. I couldn't find anything on the DUAT providers' web sites that says
they provide that service (audit trail).

In answer to the OP's question:
I like to start with a big picture like from http://www.weather.com, then I go
to http://www.aopa.org/membrs/wx and look at their graphics products, then to
http://adds.aviationweather.noaa.gov to poke around, then
http://www.enflight.com for DUAT access. I've grown accustomed to their
presentation of the DUAT data and I like it.
