I drive a lot of miles.
A Shooting brake can reduce fatigue, and add to the experience of going shooting. All while reintroducing the fun of driving in a spirited, yet comfortable, fashion. So, in addition to the joy of the shooting, you are adding in the delight of the drive. In a vehicle that pleases you in other ways as well.
People fantasize about crawling over logs, fording streams, climbing mountains, etc. but in reality, turning around in a "UP carwash" is probably the toughest thing they'd ever do. And they aren't going to drive a 50K pick up there anyway.
Most of today's 4WD vehicles are "Mall Crawlers", and the first thing people do is add low slung running boards so they can get in and out. Kinda defeats the clearance claims.
Funny story, one of the "School Mom's" at my children's school drove an H1 Hummer. Pink of all things. On a slushy day, a truck passed her, and the backwash of slush covered her windshield. Her wipers couldn't move it. So, she stopped on the side of the road.
I came upon her (all 5' of her) trying to climb her vehicle, waiting for the auto club. She couldn't reach the wind screen to clear the slush. Lotta good those planetaries did her. Mall crawler.
Going shooting is not a Roald Amundsen level expedition. I don't want to feel like I've been in a rock tumbler all night when I arrive.
