I prefer using O for attacking and X for artes, because that's the way I'm used to them being from playing Phantasia, Eternia, Abyss, and Vesperia. I got used to it being the other way around in Graces f, but that's only one where that style works for me. --- First comes love, then comes marriage, then comes adults flying through a portal in the sky. -NettoSaito on the children characters in Fire Emblem Awakening.
My first PlayStation-based Tales game was a Japanese import, so I've always opted to use the circle button for normal attacks. --- People are entitled to their opinions. Mix opinion with condescension and rudeness, and then we have a problem. Currently playing: GTAV, RE4, ToI-R, Sonic '06
Both, I guess, I just go with whatever is default, for the most part.
It does present a bit of a problem when I'm trying to juggle multiple games at once, though. Like right now, I'm trying to juggle NDX, Rebirth (when I'm traveling for work) and Xillia 2 (when I have time at home). I switched Xillia 2 to English standards since I just played through X1, but haven't fiddled with Rebirth or NDX, so most of my gaming sessions start with me emptying half my TP pool/emptying all my FGs before I remember that they are set differently. --- Koitsu wa mirai wo takusu eigo no tsurugi da! ZANKUU TENSHOUKEN!!!!
I usually leave it as default, except in the case of when I buy a game twice.
Symphonia: A = Attack, B = Techs
Abyss: X = Attack, O = Artes
Graces... you can't change it
Vesperia 360 I changed because having B as normal attacks is just wrong... B should never be normal attacks.
Vesperia PS3 I changed to match Abyss
Xillia (jpn) I left as default (and changed it to match the Japanese Default when the English version came out.) --- The more time I spend on GameFAQs, the more I realize that people are ass hats and the world is going to ****.
I prefer the American button set up that's why when I played FF7 in English that uses the Japanese setup of O = accept command and X = Cancel I had to change it to X = Accept and O = Cancel.
So once I do play on buying Xillia if X isn't already used for normal attacks and O isn't used for Artes by default I'll reverse the 2 buttons since I find it easier to use Ares = O and X = normal hits.
However if a tales of game doesn't use the L1 or R1 + O button for artes shortcut keys I will change it to use them that way.
NDX is too easy 100% job class mastery = Mel and Dio at levels over 150 (and the max level is 200) yet I still used X = fight command and O = spells/artes for its controls.
Once all jobs in NDX are mastered I let Dio use the jobs that are basically the Guy/Reid/LLoyd/Cless Artes setup let Mel be in a magic attack class job and use Cless and Mint my final 2 NDX party members.
