That is true, but if Galadriel had taken the Ring, she would be our new God(dess)!
Pffft, Galadriel may be the most ancient and mightiest of the Noldor in Middle-Earth, but even so she could never harness enough power from the Ring (which would not obey her) to stop Sauron's onslaught. Sauron's military victory was
totally assured unless the Ring was destroyed; even if the Ring were used against him. Then it would have just been a matter of time before he stripped it from the Elf-maiden, probably with his own bare hands!
Even Saruman, who was of the same stock and race as Sauron (though of much lesser stature) could have only hoped to use the Ring in a "slave's mockery" of Sauron's power -- and Saruman was considerably much more powerful than Galadriel.
That being said, Sauron himself was tiny and pathetic compared to the first and true Dark Lord (Melkor, a.k.a. Morgoth Bauglir); as even Tolkien described him thusly: "In after years [Sauron] rose like a shadow of Morgoth and a ghost of his malice, and walked behind him on the same ruinous path down into the Void."
Even at the height of his power, Ring and all, Sauron was just a "shadow" and a "ghost" of the original Dark Lord. Essentially, if we're going to worship anyone from Arda I'd go with Morgoth for you dark types, the Valar for polytheists, and Iluvatar for monotheists
PS, besides, Sauron may have had some armies of orcs and a few trolls here and there... but Morgoth had LEGIONS of orcs and trolls as well as armies of balrogs and dragons. The orcs, trolls and arguably the balrog of Moria only served Sauron because he was once a loyal lieutenant of Morgoth, but it was Morgoth who created* the orcs (corrupted elves), the trolls (in mockery of ents), the balrogs (corrupted Maiar and spirits of flame/shadow), dragons (corrupted Maiar/spirits of wyrms), and other horrible things like the spiders (the brood of Ungoliant, evil spirit seduced by Morgoth at the beginning of time -- Shelob and the spiders of Mirkwood are distantly related to Ungoliant).
(* -- Morgoth couldn't create, only Iluvatar could, but Morgoth could take that which existed and corrupt it!)
