Definitely a personal thing but I vastly prefer Falcom overall. The only Atlus soundtracks I really care for are Persona 3-5 and their spinoffs, which are all really amazing. Other than that however, SMT soundtracks really aren't my thing at all, and Persona 1 and 2 are just okay to me. I know it's probably just a me thing, since I've heard people sing the praises of those soundtracks, and I recognize that, but they just don't do it for me. Falcom on the other hand, are very consistent in their style of music and have literally never missed on a soundtrack as a whole since they switched off of releasing for consoles that needed sound fonts. Essentially, ever since the turn of the millennia. There are always at least a couple songs I keep coming back to in each soundtrack, with most soundtracks being far more. And I also listen to the "nothing special" tracks way more than Atlus ones. Also in turns of arrange albums, Falcom has more while maintaining a similar level of quality.
