So you've narrowed the list to these 2 cars?
You won't feel the Allion as an upgrade even though it has more space, but the technology and options are not even close to an aqua.
Better off with a Vezel as it has a high ride position and lot of new tech, but make sure you have some extra cash if DCT issue pops up
*Also you mentioned you concern driving pleasure ,so Vezel it is.
