Difference between ADC dual mode and 2 ADCs in independent mode

Hello, I am using STM32F3 Discovery kitand I need to measure 2 signals at the same time. It seems to me that there are to possibilities: 1) use regular simultaneous dual mode, 2) use 2 ADC's, both in regular single independent mode and triggered by the same timer.

What is the difference between these to possibilities? Or doesn't matter which way I choose for my application?  Thank you for answeres.

When they are bonded you only need ONE DMA channel/operation. It's clean and simple, and while I'm sure other methods could perhaps be employed they would seem to be unnecessarily complicated.
