rod/stroke ratio at higher rpm's...
hence the reason you see the fastest dsm's running 2.0's...since they breathe the best from 6k-10k rpm.
jerry and others running strokers are looking for useable power under the curve...which is more fun on the street.
everything is a compromise...esp with our cars...its finding the setup that is closest to your liking which matters.

Or you could ask why is the torque so low on 2.0 car? graph overlay tells the story. toms car would eat the blue car in a street race. and if blue car doesn't shift at 9000rpm there wont be a race at all. usable power starts 1000 rpm sooner on the stroker. at 5500 rpm the strokers are making 80 more hp than the 2.0. that more than makes up for the 30hp loss at high rpm.
The hp on the 2.0 was still climbing at 8500rpm. usable power 6-9000 rpm
usable power on 2.3 was 5-8000. Toms car is also undercammed for the 2.3. would easily have picked up 40hp with some good stroker cams
my car was picking up about 12hp per pound of boost. was on track to make what it made before 570/510 at 34-35psi
You are also missing the 2.0 was on c16. that is good for 40hp over 93/meth. On c16 toms/my car would make over 600hp. the torque would be stupid high. as hard as we tryed to keep my car on the rollers the front tires were shredding even in awd mode. and that was at 490tq.

Pick up a copy of current SCC. where five evos attempt 1000hp. Of the four that layed down 900whp+ two were 2.3 engines and two were 2.1 engines. Tuners have figured out how to take advantage of the extra stroke on large turbo setups. cam and cylinder head setup is substantially different when choosing a stroker.
On my recent step backwards on my blue car I am now 100% possitive the 2.3 was just plain faster than 2.0 even with smaller turbo. the 2.3 is just plain 275cc larger than the 2.0.

John sheppard was asked why he doesn't use more than 2.0. His answer was I am not done making power with the 2.0.

yes on the streets toms car might be the blue evo from a roll but from a dig I think the blue car will beat toms car but each setup suits its owner not everyone cares for the the torque down low look at Honda they run great times at the track and consistent but barely make any torque. Its like Chet states everyone has their own preference. My opinion if you want a lot of torque then you are in the wrong chassis V8 will give you that

high torque numbers are a direct indication of how fast the setup is hitting power. not a person on earth that would prefer 600hp/400tq over 600hp/500tq. I personally know five people who ditched their 2.0 for a 2.3 without changing the rest of the setup. all five were very pleased they did. make no mistake, torque is fun.
