No offense, but Kirito (and the author) knows his strengths better than you do. If he's certain that he would lose(note that he said it would be "impossible" for him to win)regardless of whether he wielded a second sword or not, he would lose. And Reki explicitly states that it would be the difference in stats that could possibly give Kirito a win, not skill. As for the reddit post, this dwelves in hypotheticals. Kirito has said that if Yuuki was trapped in SAO during those two years, she would've received Dual Blades much sooner than he did when he was in Aincrad due to her quicker reaction time and superior gaming skills. Meaning a hypothetical SAO Yuuki would stronger than canon SAO Kirito.

No matter how you want to spin this, Yuuki still comes looking like the better player.
