Pe2, Tu2 and Il4 were quite different beasts. The Peshka had overall dimensions similar to Mosquito, but was stressed for dive-bombing, and was well suited for tactical conditions on Eastern front. It had a top speed of around 350 mph and there are no comparable western bombers, the A20 was much heavier and slower.
For the Il4 a comparison may be attempted with the British Hampden or the German Do17, all non-outstanding types.
The Tu2 was a little bigger than the Pe2, and was so successful that it was built from 1941 to 1948. It was heavily armed, very manoeuvrable and able to survive heavy damage. A little smaller than the Ju88, it was faster and had better defensive armament (in my opinion, it was overall a better bomber).
All that said, I think that this kind of comparison is always subjective and questionable. Bias come often into play, and anti-Russian bias are very common.

I agree the Tu-2 was probably among the best, being able to out-turn single engine fighters. (I think the light for its size Ki-67 might have been a serious contender, even in maneuverability).

But the Tu-2 is a much later design than the Pe-2: The Tu-2 was not really in service until late 1943, and is mostly a 1944 aircraft: Not a fair comparison.

With bombload I think the Mosquito beats them all in range, and is a match for the P-38 in speed. Is range an important requirement for a light bomber?
