Meh, I disagree, I think which one you like more depends on your personality at the time. I played p4 first but got stuck because I didn't feel like grinding late in the game, decided to give p3 a try on easy and had an absolute blast. Still haven't gotten around to finishing p4. I just prefered the story and setting/atmosphere more in p3, though I do admit I found p4's cast more memorable. I'm not sure if I'd feel the same way now, as p3 definitely had a bit more angst than p4. I'd probably enjoy p4 more now, but that's nothing to do with one being older than the other, just very different moods between the two. Hoping p5 will strike a middle ground, darker than p4 but not as angsty as p3.
On topic, thanks to whoever mentioned Catherine ( I'm on mobile), I tend to forget about it but it was a great game and the bar really did feel like home by the end! I'm going to have to go with Demons Souls' Nexus as my hub of all time though.
