Since you love JRPG's, it's a no brainer. PS4 all the way. KH3, FFXV,If you like MMO's there's also FFXIV. Main Tales of series is exclusive to PS4 this gen. Tri-Ace and SE will likely have another Star Ocean on it. NIS JRPG games will likely be coming.
On top of that, Sony's 1st party studios are known to deliver more so than MS rather then just sequel after sequel. Not that Sony doesn't do sequels either but if you've noticed last gen, the creative ideas, risk and new ip's happen more so on Sony's side. This is something that even Phil Spencer admitted and admired about Sony. If your into multimedia, then apps such as Netflix are superior as it's not behind a paywall unlike X1. You'll also save $100 on the cost of the console and get superior multiplats that you can install and play in minutes rather then waiting 25-30 minutes for the game to install on the Xbox. Also, if you look into PS Plus that's an incredible value where each and every week you get game discounts, free game downloads with recent games that are very popular such as Bioshock Infinite, Tomb Raider etc rather than 6 and 7 year old games on the Xbox. Now you do get to permanently keep those 6-7 year old Xbox games rather then the renting style of PS Plus but the quality of games is worth it.
If your more into multitasking like watching TV and Skyping then get the Xbox then.
