My house has a Move, the pointer controls are fine but just a bit delayed. Don't navigate the Playstation Menu with the controller its to hard, but it is pointerless. Sports Champions is their casual title, and something I like a lot better about it is that each sport has a lot more depth then it's Wii equivalent.
As far as quality of motion controls, I'd say its as good as WM+ but not much if any better.
Do they really have more depth, though? I mean, does Disc Golf have anything more to offer than what's on Wii Sports Resort? While the gladiator mode has a shield, does it have the parrying ability that the WSR mode offers, to give patient players an advantage? Even though there's more and varying archery targets in archery, does it match the tactile feel and true, not cheap, difficulty of the WSR version? Does Table Tennis even work on the Move? I suppose I can't criticize everyone's favorite game: Bocce Ball. You got me there. Of course, WSR has golf. And bowling. A competitive Disc Golf mode with targets and such. Also, basketball and more. They might appear shallow, but they have a certain depth to them that I didn't experience or observe whenever I've dealt with Sports Champion's offerings.
Gladiator offers a shield, different fighting styles from AI, actual tactics, a powered-up attack, a usable versus mode, jump attacks, ring outs, rolling get ups, and other additional moves.
I know WSR offers tons of sports, but I would have appreciated some real good depth in a few of them.
