It's not just that it's "mature" like Monster, it also has that classic early 2000s animation while Brotherhood is more modern and soulless, FMA 03 and Monster are almost contemporaries after all, with the latter only coming out in 2004. Also compare it to Kino's Journey (2003) or Haibane Renmei a bit earlier (2002). God what a soulful era of anime
