The best Jet bomber Tu-160, B-1, B-52 and aircraft type in extiction

Which jet bomber has the best record, i love the Tu-22M and B-1B but i guess many consider the B-52 the best bomber ever.

Old bombers like the B-47 or Tu-16 are interesting designs but the new B-2 will make think many that is the best bomber ever just by stealth.

The ultrafast B-70
