FYI, all of their apps are on sale. Some are just a buck off but that's the case with a couple you listed so I'm assuming a sale is a sale to you. Even their newest one is on an intro sale, so you might as well just check the "best Kemco" thread(s).
Fantasy Chronicle is my fav and is on sale. It looks like they may be abandoning their occasional $.99 sales, which is a good thing in terms of them being able to keep on going. I'd like to see them get a bit more adventurous in their next endeavors. One of those is their first attempt at a 3D RPG and looking forward to seeing how it turns out. While all of their RPG's have their own charms and decent storylines, they don't stray too far from the standard mold. I still enjoy them though.
BTW, if you want a fun JRPG with plenty of humor and quality, I'd check out Doom & Destiny. It's not Kemco, but it's a blast and only $.99 at the moment. Kemco will more than likely run sales again.
Yes true, thanks for the feedback guys, I went for symphony of eternity, I'm just discovering kemco, their ausome, and much cheaper (and worse quality...) than square enix
