The maximal takeoff weight, т
Тu-95 - 187,7
B-52 - 220

The maximal speed, km/h
Тu-95 - 925
B-52 - 1000

Fighting radius, km
Тu-95 - 6500
B-52 - 7210

The maximal range, km
Тu-95 - 15 000
B-52 - 15 000

Operational ceiling, m
Тu-95 - 12 000
B-52 - 17 000

Cumulative thrust of engines, kg\sec
Тu-95 - 40 000
B-52 - 61 600

Arms, kg
Тu-95 - 11 340
B-52 - 20 650


There is such concept, as economic efficiency. Cost of one Tu-95MS in tens times is less than B-52. Thus, for the same sum, that you spent for one B-52, we could construct ten Tu-95MS.
And now compare one B-52 bears 20650 kg of bombs, and ten Tu-95MS bear 113400 kg. Economically Tu-95MS is more effective.

PS: It reminds me dispute about modern diesel submarines.
Then if that's the case, of being cheaper, maybe the U.S. should start to consider building old WWII bombers to cut costs!
