I can say that after using a task manager since I bought my phone in December, I finally got rid of it only a few days ago and I immediately noticed a drastic increase in speed with running and using applications. So there is definitely a speed improvement.
I would say it's because the apps are constantly running, therefore you do not have to re-execute the application continually which is what is slowing the phone down.
However, it looks like my phone is using more battery.
