On the basis of the above figures, the B-52 has a slight speed advantage , service ceiling. it has a cimb rate 3 times better than the russian aircraft and carries over twice the bombload.
The Soviet aircraft has a much greater range, and this seems to have been exploited in its adaptation to maritime strike and recon roles.
Hard to know which aircraft has the better avionics fit. I think both aircraft are unable to operate in environments where enemy fighters are present....they both are highly vulnerable. this includes vulnerability to Surface to air rockets.
Back in the 70s, Bears were present in the Indian Ocean. When the russian invaded Afghanistan, they used their bears, based in Aden, to try and deter Allied naval incursions into the Arabian Sea. at that time AFAIK, the HMAS melbourne was the only carrier present in that area, escorted by two AAW ships, and 3 or 4 other escorts. Bears would fly in groups of 10 or so, with theoir long range stand off weaponary (despite being pretty innaccurate) the only defense we had were the 8 A-4s were had on board. Our A-4s at that time were not configured as bombers....they were mainly used as sir defnce aircraft, but they had a hard time achieving interceptions early enough to prevent launches of the soviet stand off weaponary. We expected them to fire these things in salvoes, because most of them would miss. However, every time we achieved an interception they would always turn away. they knew we were fair din*kum, and if they entered the fleet protection zone (cant remember, but i think it was 320km) we would shoot them down. It was a time the world came close to an actual shooting war, and we didnt know it.....
I have a healthy respect for the Tu-95
