Vauxhall Astra Sports Tourer - Astra auto Tourer vs Focus auto estate - bentley nut

I am due to change my Kia Ceed diesel auto estate next year and have been disappointed with the hard ride and poor MPG.

So looking at either an Astra Diesel Auto Tourer, or a Focus Diesel Auto Estate, so which is the best one?

Note I carry a powered wheelchair (75 kilo) in the load area, drive around 13k each year with a fair mixture of both Rural and City driving.
