If pressed to choose, who do you think Anakin would choose between Obi-Wan and Padmé? Do you think that choice would change depending on the circumstances?
Hands down Obi-wan. Even if you don't ship them, even platonically this is pretty much canon.
And I say this because that's literally WHAT he was doing by remaining in the Jedi Order (which he had severe issues with). Sure, Anakin loved the heroism and was beholden to the promise made to his mother that he would remain in the Order. And yes, he truly was a good person who valued doing good and his Jedi training -- however, it is undeniable that interwoven in ALL those things was... Obi-wan.
Obi-wan who was his cogeneral in the Clone Wars, the two of them side-by-side known as the faces of the Front.
Obi-wan who promised to train him so he could fulfill his mother's wish.
Obi-wan who seemed to so easily exemplify the great Jedi mediators he knew he could never be.
Obi-wan who was essentially Anakin's walking-talking moral compass.
Anakin didn't leave, despite his marriage, despite his children, despite his deepening disgust with the Order because of Obi-wan (and Ahsoka).
Anakin loved being a Jedi but what he loved more was being a Jedi with his Jedi family (Obi and Soka).
This was a major source of mental contention for him - choosing between these two "families" he created in equal but opposite worlds. His marriage to Padme, who was directly linked to his mother's death (she was the only one who knew he murdered the Tuskens, so the only one he felt forgiveness with) and so he refused to let go of her. He saw Padme as a Judge of the moral fortitude of his curated jedi knight Image. If Padme, stalwart guardian of the lawful Senate, forgave him for this atrocious crime - then surely he wasn't a monster.
And on the other hand was his "marriage" to Obi-wan, an uncommon war-borne partnership resulting in the Padawan they both trained and the war they bore on their backs. Their closeness was highly unusual for the Order - but the Order couldnt do much about it given their reliance on them as generals and the chaotic state of the Republic. A lot of oversight seems to have fallen away, and I'm sure a part of all those on the Front felt closer to their compatriots and the clones than the Council comfortable in Coruscant, as they trudged tirelessly and endlessly through distant worlds fighting tooth and nail in the trenches.
If pressed to choose, which he essentially was (and Sidious manipulated his years-long strife) he would pick Obi-wan. He proved this by not leaving - even though by all accounts he should have and simply started his own Order. Something was keeping him there and it wasn't just the war or the heroics - Anakin couldn't leave Obi-wan.
There are numerous instances of your exact question in canon such as in Stover's novel where Anakin ponders if he loves Obiwan "more than his wife" at Sidious' pressing. Also the Son on Mortis revealing himself in the image of Anakin's mother Shmi and saying that Padme was not his true love but essentially a lie -- a pretty damn harsh summation put to screen if you ask me.
Anakin struggled with the choice between Obi-wan and Padme (and what they represented) for YEARS til the very end at Mustafar, when finally, at his mental breaking point - he chose himself.
And Sidious was counting on that.
