Their seating or slope roof instead of rear cargo space. The current crossover version of the outback fits way less stuff in it when you go camping then my 4th gen legacy wagon. There's a little more room for people but even with the seats folded down my legacy wagon fits more than the crossover.

There's so much space taken up by interior trim and sloped body areas for no reason that could be used for cargo.

Edit- On the performance front the new XT can accelerate, but it feels bad to drive, wobbles in the corners while bouncing on the road, and does not stop well. It has similar ground clearance with the same sized tires as my legacy and less than a legacy outback stock for stock. So I just don't get why you would pick the crossover if given the choice. It is also always fun to see the new Subaru dig a rut into a hill on a dirt road if they forgot to get a running start while I can climb it with my real AWD (VTD center diff.) Even old base models with 4ACT can shift into 4x4 mode (if you shift to 1 or 2 it locks the coupling if the steering wheel is straight so you essentially have a transfer case.)

The 2.5i withe the CVT is what I do not like. The 2010-2019 outback 2.5i take over 10s for 0-60, and the rest of the lineup was similar. They re-tuned the CVT to be more aggressive off the line so it is like 7.5-8s not for most of the NA line up, but the 5-60 is still over 10s. I had a 2017 impreza long term loaner and it felt unsafe to merge onto the freeway from a metering light in the bay area. It also got worse city MPG than my tuned LGT in the hills.
