I've been doing a little tinkering in CarTest2000 software for these cars, and here's what I've come up with.
The Accord V6 makes 240hp/212tq or 250hp/222tq depending on what kind of fuel is in the tank. It will pickup another 10hp/10tq on premium since that allows it to run a little more ignition timing advance before it starts knocking. So that's why there are two Accord V6 models...
I was looking mainly at the sedans, since I'm a sedan guy, but I used the 2002 Camry V6 4AT, a 2003.5 Camry VVT-i V6 5AT, and then a 2004 Camry SE V6 3.3L 5AT (assuming 2003.5 gearing carries over) for the comparison.
Looking at the time-to-distance columns, the superior torque of the 3.3L engine and more aggressive gearing has the Camry/Solara 3.3L out in front of the Accord V6 until around 70-80 mph. After that the Accord's better top-end is finally kicking in and it starts pulling, passing, and then walking away after that. Edge goes to the Accord V6 at the 1/4 mile mark. The 3.3L just doesn't have the legs at the top-end to stay in front, but it's ahead before that and just gets passed a few hundred feet before the line.
So the 3.3L Camry/Solara should be able to whoop some torqueless Honda butt

, but not on the highway. Stoplights and acceleration from lower (legal) speeds is the Toyota's domain. Acceleration at higher (illegal) speeds is the Honda's domain.
IMPORTANT NOTE: The acceleration times are estimated assuming the 16" wheel/tires that come on the Camry. Since the Solara V6 SE Sport and SLE models are all coming with 17" wheels standard, that means that these models will have more unsprung weight and inertial resistance to acceleration than the 16" models. I've found that 16" wheel/tire combos generally weight about 42lb. 17" wheel/tire combos generally weight about 50lb. A good approximation is that for every pound you add to your wheel/tire combo, that's the equivalent of adding 8 pounds to your car, and you also have 4 wheels and tires. So assuming an 8lb difference per corner, the 17's will have the affect of adding about 250 lb of translated weight to the car.
That means that a Solara SE V6 with the 16" wheels and tires will probably accelerate noticeably quicker than the SE Sport or SLE models with the heavier 17" wheels and tires.
How much? Tough to say. Torquier engines are generally less affected by heavier rims, so it might only be a 6:1 ratio. Honda's (torqueless) are generally more affected and a 10:1 translation might be more accurate for them. These are just approximations, so take them for what they are until people actually start hitting the track.
Adding 250lb to the Camry 3.3L model accounting for the heavier 17" rims gives the following results...
0-60 mph: 7.00s (what Toyota has stated)
0-60': 2.40 @ 31.20 mph
0-330': 6.57 @ 57.65 mph
0-660': 10.07 @ 71.19 mph
0-1000': 13.09 @ 82.54 mph
0-1320' : 15.60 @ 89.85 mph
Now looking at the results again, the Toyota should still be able to pull off the line, but the crossover point is now just moved back for 17" models. 330' and about 60 mph is where they are even, and the Accord V6 is pulling away steadily from then on. Note that the only Accord V6's to come with 17" rims are the 6MT models, which are pretty rare. All others have much lighter 16" rims.
