Definitely classic > other two packs.
Classic has way to many staple cards compared to the other two.
Get adventures done %100. Guaranteed valuable legendaries that you cannot get anywhere else. Packs will giv e you some legendaries here and there but its a long shot to recieve a useful one for you desired class etc. On the other hand adventure awards are used in almost all decks?*
