I was asking about mission capability, not numerical differences. For example, just because the TU-22 can fly 500m higher doesn't necessarily give it any practical advantage.The Tu-22M has much better speed and performance. Higher flight ceiling and better range
An extra 400km combat radius would allow slightly further inland basing/pacific reach. Actually on this point, some sites give the H-6 a 3500km combat radius
Being supersonic does allow the TU-22 to reach targets faster and sortie more often.
