Oh yes, Thingol was of course not flawed

That Elrond distances himself from the Noldor because of their past, makes me almost not liking him (almost!) If it wasn´t for the Noldor leaving Aman despite the Valar cammanding them to stay, there would be no Elrond. One could ask for a little more respect regarding his Noldorin ancestors.

I wouldn´t call them flawed (except Feanor and his sons), I would call them people with character.

Part of the reason Arwen was so great was her descent

Oh please really, where was Arwen "so great", she just happens to marry the King of Arnor and Gondor. Origianlly he would even have married Eowyn.

In fact his quote about Elrond having the best chance out of anyone except the Maia suggest Elrond has a greater innate power.

Of the others only Gandalf might be expected to master him – being an emissary of the Powers and a creature of the same order, an immortal spirit taking a visible physical form. In the 'Mirror of Galadriel', 1381, it appears that Galadriel conceived of herself as capable of wielding the Ring and supplanting the Dark Lord. If so, so also were the other guardians of the Three, especially Elrond. But this is another matter. It was part of the essential deceit of the Ring to fill minds with imaginations of supreme power. But this the Great had well considered and had rejected, as is seen in Elrond's words at the Council. Galadriel's rejection of the temptation was founded upon previous thought and resolve. In any case Elrond or Galadriel would have proceeded in the policy now adopted by Sauron: they would have built up an empire with great and absolutely subservient generals and armies and engines of war, until they could challenge Sauron and destroy him by force. Confrontation of Sauron alone, unaided, self to self was not contemplated. One can imagine the scene in which Gandalf, say, was placed in such a position. It would be a delicate balance. On one side the true allegiance of the Ring to Sauron; on the other superior strength because Sauron was not actually in possession, and perhaps also because he was weakened by long corruption and expenditure of will in dominating inferiors. If Gandalf proved the victor, the result would have been for Sauron the same as the destruction of the Ring; for him it would have been destroyed, taken from him for ever. But the Ring and all its works would have endured. It would have been the master in the end.
Gandalf as Ring-Lord would have been far worse than Sauron. He would have remained 'righteous', but self-righteous. He would have continued to rule and order things for 'good', and the benefit of his subjects according to his wisdom (which was and would have remained great).

It says "IF" Galadriel could, Elrond could too, but that is not the case.

Here's that next line...

But this is another matter. It was part of the essential deceit of the Ring to fill minds with imaginations of supreme power.

It says Galadriel thought she could, but that was because of one of the Ring's key powers - deception. Galadriel was deceived into thinking that she could use the Ring for herself, so was Elrond, maybe even to a greater degree.

That doesn´t make Elrond more powerful than Galadriel, actually i think it´s very unlikely that Elrond has more innate power, when you have in mind what Tolkien has written about her in comparision to Feanor.
