Diesel engines do have better low-end torques but a much lower max RPM
(often limited to 4-5000). You get better MPG as well for two reasons:
Diesel holds more energy per gallon and diesel engines can exploit it
better due to the higher compression. Both combined get a 30% improvement.
When I overtake a car with my 120HP 2.0 gasoline car I'll switch back a
gear to start at around 3000 rpm when accellerating and will top out
around 6000 rpm. With the diesel car I'll start at 2000 rpm and will top
out at 4000 rpm. The net performance effect is the same. Both cars weigh
about the same (1400kg). The gasoline car gets 27MPG, the diesel is at
40MPG. To be fair it has to be said that the gasoline car has around
100kMiles while the diesel is at 20k.
On the pollution front the main problem is the high sulfur content of
diesel in the US. It also looks like that the way the EPA measures
pollution puts disels at a disadvantage (diesels produce more of what
the EPA judges worse and less of what is sanctioned less severely).

Re: Diesel engines: better low-end torque?
I was in San Diego last weekend and drove my dad's "new" 92 Dodge
turbo-diesel pickup. Unlike my vw, it blows one hell of a cloud when you
stomp on it, but since it is only intended to be used 2 to 3 times a year
towing an 8000+ Lbs trailer, it's pollution is insignificant.
As to the initial question, in comparison of equal displacement gas and
diesel engines, the diesel will produce more torque, less horsepower, and
burn less fuel. The diesel will be capable of pulling heavier loads, if
geared equally, but the gas engine will accelerate better.

A third advantage is that engine longevity on Diesels is almost
inevitably better-a lot better-than gasoline engines. Most of the
indirect injection mechanical diesels sold in cars and light trucks
far outlived the chassis in which they were sold. The Benz engines are
the only ones commonly left, aside from a few VWs.
