The 2.0T clearly makes more low end torque than the IS350. It's peak torque is round 3500rpm or so which is well below that of the IS350.
Neither of those graphs is correct, not sure where you got them. Hyundai states the Sonata turbo puts out peak torque of 269 at 1750rpm. The dyno you found is way off.
For the Lexus, peak torque is 277 at 4800, and it's an incredibly flat torque curve, already been posted.
I like my Sonata 2.0T, but eyeing a 2013 Taurus SHO with twin turbos. Going to tune it for another 100HP. I love turbos!
The Sonata's platform sucks when making 300HP or so. Can't lay the power down. Guys are in high 13's if they are lucky (most are very low 14s) trapping 103 or so.
Minus the transmission issue Ford refuses to acknowledge, my '10 SHO is one of the most fun cars I have ever driven. It "feels" like it is pulling all the way through the power band and mine is 100% stock.

Here is another set:
Hyundai Sonata 2.0T dyno chart provided by PoweAxel (reputable tuner):
Again, torque figures show the Hyundai defintely produces more low end torque. That's actually one of the lower reading Sonata dyno's I've seen. I'm fairly certain that torque figures are kept low too for transmission preservation because that same turbocharger produces a lot more torque in other applications.

Uh, the torque figures on both those graphs are practically the same at the same rpm. I don't think you're reading the top graph right. The torque figures are on the right, and they show about 220 ft lbs at 3750 rpm for the Sonata. The IS350 dyno also shows about 220 ft lbs at 3750 rpm.
Sorry dude, it's not low end torque that makes the Sonata feel faster. It's the power delivery.
But below 3750 they are not equal. That's where the low end is. Cruising in traffic at 2k rpm, the Sonata will feel quite strong getting up to speed compared to the IS.
I'm not discounting that power delivery plays a role since that low end torque is what defines many turbos power delivery characteristics.
You're missing torque, particularly in the low range. That's why I love turbo cars. You get a crap tone of torque and with a larger turbo it just keeps pulling like a train.
BTW, if your friend flashes his Sonatas ecu he can get 300whp from that stock turbo. It's nuts for a family sedan.
The same can be said for a normally aspirated engine that has enough power. For example, my wife's 2010 Toyota Rav 4 V6 will push me into the seat if I press the pedal to the metal, and there is nothing special about this car. But Toyota does not offer the same motor beginning in 2012, I believe.

3750 is not the "low end", not that torque really matters at that point as horsepower becomes the primary motivator.
I just test drove the Sonata 2.0t and it pulls hella nice. When your doing 80mph you can just floor it and it pulls crazy without needing to downshift!
My IS350 would have to downshift from 5th to 3rd in that situation

my IS350 has a more powerful version of your 3.5L.
Try the Sonata 2.0t and it pushes into seat pretty hard without revving its nuts off. Just like the Tesla Model-S feeling.

Sigh. You're right, they're not equal. Look at your graph again. Both dyno charts start at about 3250. The Lexus has a lot MORE torque at the beginning of the graph than the Sonata does.
