Waiting2goback...I don't want to seem like I am picking on you but I do want to correct a couple of things for the OP.
Nope. Wine & Dine is also a night race.
This is also not correct. The morning races (WDW Half and Princess Half) are big, but Wine & Dine is smaller (~14,500 runners last year).

OP - I haven't run the ToT 10-miler year but I did run W&D last year and am running it again this year. Couple of things to think about...
1. Time of year - does early October or early November work better for you?
2. Theme - ToT will have Villians on the course and at the after-party, where W&D is more of a mix of characters on the course. This also ties into the swag (shirt, finisher medal) that you'll get.
3. After-party - ToT in DHS with Villains vs. W&D in Epcot with the Food & Wine booths
4. Courses - this, to me, is the biggest reason why I haven't run ToT yet. ToT starts at the Wide World of Sports and only goes through one park - DHS. Wine & Dine also starts at Wide World of Sports, but it goes through 3 parks: Animal Kingdom, Hollywood Studios (with Osborne Lights - unless those go away at some point) and Epcot.
I'm definitely planning on running ToT at some point but the W&D course seems better to me.
