You did not include any combo builds of Oath. I have been playing Saheeli Rai Oath with great success and I know that the old Brian Kelly Salvagers build is still OK. I have seen Paradoxical Oath on MTGO and it did win. I am not sure if these are of any interest to you but the style of these decks are very different since they win in a very different ways and fight the field in very different ways.
I look at Oath as 3 types of decks - Control, Combo, and Planeswalker
The control builds have the core counterspells - 4 FOW, 4 MM, 2 Flusterstorm and 2 creatures plus some defense.
Combo builds vary greatly with Time Vault, Yawmoth's Will, Paradoxical Outcome or in my case Sun Titan and they have some way to lock the game down for a combo style finish.
Planeswalker builds are the Brian Kelly style decks with Inferno Titan and 3 or 4 differrent planeswalkers.
I have built all of these decks and I have tested them on paper. I do not play Oath on MTGO for various reasons but I am seeing that you may choose a different style of Oath based on where you are playing the deck.
The combo builds compete well against Shops, Dredge, and other combo style decks like Paradoxical Mentor, but these builds have some trouble with blue decks depending on you decks counter package and defenses.
The planeswalker deck appears to be the most versatile against the field but they are also the hardest to play.
The control style has issues with Shops and Dredge but plays well against blue and combo.
I do not like the idea that there is a best deck here, just like several Shop players and Dredge players will tell you there are several versions of those decks that perform differently in the meta-game.
