No. This one had better animation, battling, emotion, characters, and strategies than all those.
Take off the nostalgia glasses.
But for heavens sake, however this battle is the best one or not is entierly up to each person to decide. You can´t tell people what to think just because you sees this battle as the best ever. Nostalgia or not every each person may have a special favorite that they put above this particular battle. So stop wasting post and forum- space on meaningless posts trying to convince people of what is right or wrong.
On topic the, yes
for me this was the best
battle in the series history. It had everything Ash vs Gary had and more. Perfect musical score and epic Pokémons to fight. We got to see Ash and Paul at their best, using every trick of the trade that they knew of. Aside from Torterra Ash used his Pokémon and their capabilities to the limit and fought in true Ash- style (many flying or fast Pokémon) while Paul tried his best to lure Ash with a few Pokémon that was not the usual Paul- Pokémon (heavy tanks). And in this he almost succed in taking down what was probably the best field line- up Ash has ever started with. How could such a fight not be epic? All the crap about Paul not using the a- team is nonsense, you start with the line- up you think can win, and then there is no such thing as the a or b team (and Paul ONLY starts with Pokémon that he is absolutly secure with and who has been through his rigerous traing).
The Ash - Gary Johto- league battle, Ash last battle with Brandon, Ash vs. Paul first 6 on 6, Ash vs. Drake and a few other battles are personal favorites. The one against Gary still top my most memorable list, because it was Gary, a person he had been behind for so long and now finally defeated him, He fought not just Gary there but also took his first step from being an ordinary trainer to someone who could actually make it, to the top spots in the tournaments. Against Gary he saw that he could do
IT. That battle was more of a turning point than this against Paul. Had Ash lost to Gary he would forever been behind.
The most important thing in this Ash - Paul league match is that Ash and we other saw that his traing was the right one. That you could succeed with his style of training. Then this was played out perfectly in terms of feeling and animation and musical score.
