Normally, I wouldn't even ask that question, but Brady is coming off a BYE and could possibly be rusty (yeah, I know... hahahaha) and Warner is going up against the Bengals defense.
The safe bet is going with Brady, and Warner could possibly be knocked out of the game if that left arm is hit just right. But he's got the potential to put up some gawdy numbers tomorrow.
I was hoping this was a joke when I seen the subject lol...
I'll just say this.. Start Tom Brady.
It's not too far fetched. Brady tied his "worst" fantasy game this year against Indy and then went into the BYE thinking about it.
Warner last week had 18 points (ESPN league) against a relatively better defense than the one he'll face this week.
That being said... I'll probably start Brady.

It's not too far fetched? C'mon...
Tom Brady is putting up record numbers, and his "worst" game against Indy still had 3 TD's and 255 passing yards, and got me 25 points in my yahoo league that week, and the only thing Brady "thought" about going into the buy week was that they beat Indy and are still undefeated...Basically, benching Tom Brady at all this year would be a crime.
Kurt Warner is not even owned in the majority of leagues. He's washed up, has a bum left arm and is on a bad team.

Ok, ok.... lol I'm starting Brady.
Just know that if I lose for having not started Warner I'm going to come looking for you. 
No-brainer. Don't give that much consideration to outside influences like matchup, bye weeks, etc. At QB, start the more talented player (at least fantasy-wise, which usually isn't too different from "real life") every single time.
I'm never giving advice on who to start in fantasy ever again. lol
I'm just happy as a peacock that I started Brady.
I don't know...Brady's been kinda off tonight. He's missed, what, 4 or 5 passes in the first half? What the hell is he doing out there? LOL

Not whole heckuva lot. Just keeping pace with that whole "shattering Paidtons TD record" thing...
