To explain my position better I'm saying it from the perspective of someone that generally does the platinums for these games and I always regret putting my first playthrough on anything but easy. Reason is normal isn't a challenge and hard makes it tough to get certain battle related AP points.
So what ended up happening for me in cases where I did that was that hard was a real struggle until I had all the quartz to break the game while trying to get all the necessary AP points and normal just ended up being a higher time waste that was about as satisfying as playing on easy.
That's why I recommend easy if you're going for 100%. Makes it possible to rush through stuff better. The challenge playthrough is generally nightmare.
If you don't inherit levels even with all the right quartz it can generally be pleasantly challenging although well it's a JRPG in the end challenge is just about knowing what to do, given there's no execution pressure.
I've never gotten the platinum for any game. >>; Would like to one day, but then I never get around to it lol.
