Aarioniero managed to incapacitate Rukia while nearly succeeding in using psychological warfare against her. He just let his guard down at the end.

Szayelaporro trashed a lieutenant and a Quincy, Mayuri's tactics and intelligence just exceeded his.

Zommari gave Byakuya a good fight. Byakuya was simply the better warrior.

It took Kenpachi, who can usually dispatch opponents in seconds, several chapters to overcome Nnoitra. Not an easy kill for him by any means.

Ulquiorra was only defeated by Ichigo level 2 hollow bs

Halibel survived one of Hitsugaya's ultimate attacks and faced three powerful Shinigami on even ground before being stabbed in the back by Aizen, who used Kyoka Suigetsu to warp her perception.

Barragan had to be outwitted by two Shinigami opponents who sacrificed their arms to defeat him, and he was killed by his own power, not theirs.

Starrk managed to get the upper hand on FOUR captain-class Shinigami who, like Barragan, had to resort to tactics and trickery to wear him down.

So yeah, I don't see how the Arrancar were defeated so easily.
