For Single Player ONLY... Virtua Tennis 3 or Top Spin 3?

I never play online, so I'm only concerned with the single player "Campaign," or whatever the game calls it. I like the sound of the VT3 controls better, but I'm worried about how much I'd like the campaign since the review makes it sound like there are an extremely limited # of computer-controlled players. I'm worried that would get repetitive and boring.

Any thoughts, especially from those who've played both? Though I'm interested in what anyone who's played just one of them has to say too.

I played the Top spin demo and it made me wanna buy it and ive never played a tennis game before and i was kind of into it. I never played Virtua Tennis but my Opinion is to get Top Spin.
