I don't see how anyone can comment on either being good or bad without actually using either product.
But we can speculate on what we've seen, mind you, if the aim is about expanding your userbase and tapping into the casual market, despite how good/bad we think they are at E3, it won't matter too much, the 'casual' gamer won't have seen it.. it really depends on the press/journo's and the marketing departments.. in which case ,they tend to have a more balanced view..
