I guess I feel satisfied enough to state that I find the Tu-2S to be a bit better than the A-20G in the anti-armor role. The main advantage is the lethality of the Tu-2's bomb load. Three 1,000 kilo bombs almost assures 3 kills. Four 500 kg bombs will usually get 4 kills. You simply don't require the precision needed with the A-20's 500 lb bombs. You can toss a 1,000 kg bomb near a Wirble and kill it, as opposed to having to put a 500 pounder close. Thus, you can drop from greater heights, reducing risk.
Air to air, it's probably a wash. The Tu-2 turns smaller circles, whereas the A-20G rolls much better. However, the A-20 can rip off wings much easier, and can't come close the Tu-2's dive speeds. In contrast, the A-20G is more maneuverable at medium speeds, because the Tu-2's controls really stiffen up above 300 mph. The A-20's concentrated 6 fifties are very effective against aircraft, nearly as effective as the Tu-2's two 20mm cannon. The greater firing duration of the A-20G means you can fighter longer. One must pay more attention to ammo use with with the Tu-2. I won't compare defensive guns, because I'll never fly either of these in a manner that would have me using the defensive guns. Both are vastly better served by maneuvering and dogfighting. That doesn't mean I won't use the Tu-2 for level bombing. It means that I'll never fly formations. At over 6,600 pounds of bombs (same as a Ju 88, but far faster and more maneuverable), a single Tu-2 carries more weight of bombs than a formation of Bostons, Bettys, or Ki-67s. That means it can kill a Cruiser, and still get 50% of the bomb total needed to sink a CV in one pass. After that, it can go to fighter mode and give a very good account of itself.
The Tu-2S is a great addition to the plane set....
