wii grand slam sports

Is a golf video game so much fun that it actually has a lot of replay value?
SHould I wait to get motion plus with red steel?
How are the controls on Virtua and Grand Slam? I saw a oneup video showing the controls of Grand Slam and it looked horrible and seemed like a sooped up wii sports tennis. I've read that Grand slam has even better contols than Virtua so are Virtua's really bad?
I just don't know which game to get! Tiger Woods seems like it has much more playability with all the modes and such compared to other games but is playing golf on the wii that much fun that you want to play it over and over again? the competetive aspect of tennis seems like it would be more entertaining but not if the controls aren'w good. Especially in Grand Slam which only has tennis modes to play unlike Virtua with its mini games. Any help guys?
