Your figures are meaningless in context without knowing how many were lost, and what the operational cost was per tonne of ordnance.
In WW2, after the Battle of Britain the most successful British aircraft was probably the twin-engined Mosquito, an early stealth fighter/bomber. I was taught at school by the former wing commander of a Mosquito wing, and he told us that flying Mosquitos was considered a real privilege because you expected to survive the War. Mosquitos could fly to Germany, pathfind for heavy bombers, do a little precision bombing themselves and be back in time for breakfast, even if someone put a shell in an engine while over the target. Single engined fighters and 4 engined bombers had far higher loss rates.
The significant point is the kind of opposition you could expect. Bombing Third World countries is a bit different from bombing First World countries.
