Topic on Talk:Mobile Suit Gundam: The Witch from Mercury

The official site offers two slight variations of the key visual [https://en.gundam.info/about-gundam/series-pages/witch/shared/img/top/visual_main3.jpg one for landscape] and [https://en.gundam.info/about-gundam/series-pages/witch/shared/img/top/visual_main3_sp.jpg one for portrait] (which can easily be cropped for a more square image due to the dead space). Which one would be better for the constraints of a page image?
