Estate.
I've had a lot of cars over the last couple of years through work - A3, A4, A5, A6, Octavia, Superb, Fabia, 1 Series - and the biggest factor when it comes to transporting gear is how easy it is to get in and out of the boot. An estate with a flat loading boot is unbeatable IMO. When I have to buy my own car again that's what I'll be looking for.
The Skodas are unbeatable value for money IMO - they feel as good as the Audis but less than 2/3 the price, especially the Superb, great car.
