I know this may come off blasphemous to some people but I dont like the fact that fallout is just a reskinned oblivion (which i did not care for). Borderlands has better controls, more weapons, online co-op, and just all around looked better to me. It does lack a story but when they come out with the sequel and the story is there it will blow Fallout out of the water.
I think you are onto something with the last question, to me they are probably too different to compare. I have a great fondness of Jrpg's from when i was younger but now days im probably more prone to enjoying a "western" rpg. I am playing FF13 though and I am enjoying its so far. but to compare it to a game like Fable would be hard to do. For me anyways!
i think the main protaganist should lead a unit down the battlefield. leveling up would be done by crossing the end of the battlefield with the score orb. Shoes with spikes will be worn as well as padded armor. If final fantasy did this, then it would truly be great.
