As far as I know, Porsche has a higher grade.
Brand status: Porsche is regarded as a super manufacturer, famous for its high efficiency, high quality and high technology. In contrast, Land Rover's reputation and status have declined, and it is regarded as a second- or even third-rate car brand.
Product positioning: Land Rover focuses on the SUV (off-road vehicle) market, focusing on urban SUVs that are comfortable, luxurious and superior in performance. Porsche is known for its top-level horizontally opposed engine technology, which is comparable to F1 giant Ferrari.
Technology and innovation: Porsche is the only brand in the world that is qualified to be compared with Ferrari, with top-level horizontally opposed engine technology. Land Rover is the only company in the world that specializes in producing four-wheel drive vehicles.
Global reputation: Porsche is considered a world-class top car brand, while Land Rover's reputation and global influence are relatively small.
