The Spanish edition of Rolling Stone ranked it forty third on the magazine's 2006 list of "The 200 Best Songs of Spanish Pop-Rock". In the song's entry, Miguel Ángel Bargueño felt that "Porque te vas" "broke the image of folk balladist that Jeanette carried since her Pic-Nic stage and conveyed an accentuated feeling of loss that caused a greater impact by being interpreted by a helpless-looking twenty-year-old." In 2014, Diariocrítico.com placed "Porque te vas" at number fifty four on its list of the 100 best songs of Spanish pop. Writing for The Guardian, Andrew Khan described the song as "a masterpiece of downbeat easy listening," and praised it for "[proving] once again there's often more depth of emotion in derided MOR pop than other, more fashionable, genres."
