I'm looking forward towards this game and I want to get an opinion from the people who played the japanese version or those who've only seen it as to which one is better since I can't decide. Sorry if I spelled the name's wrong I get confused because of the name change.
Second, I suggest Greiga (Which is dubbed Gregar). The crosses are better (IMO), which is the only real difference between the versions, except for the final boss. Greiga and Falzer (as bosses, that is) are both equally easy, so no need to think about that. The only other real difference between the two versions (besides coloring and things) is:
A secret boss, Forte, absorbes one of the Beasts. Depending on which version you get, Forte absorbes the OTHER beast (Like if you have Greiga version, Forte absorbes Falzer), and his attacks are slightly different.
