Even though they were trained in using the Bankai they stole, according to Cang Du, Vollständig is their own power, and logically they should have tons more training with it. Anyone would prefer their own technique over a stolen technique they have much less training with.

One exception could be Cang Du - he could have easily killed Hitsugaya with the short training he had with Daiguren Hyôrinmaru, but Hitsugaya was already injured and defeated by Bazz-B before Cang showed up.
