TSR-2 and F-111 served different strike concepts

Would the BAC TSR-2 have been a better strike aircraft than the F-111 Aardvark if it had not been cancelled?

They were designed around different roles: the F-111 emphasized forward-deployed strike, while TSR-2 carried a more strategic British concept.

TSR-2 and the F-111 are compared here through the missions each was intended to fulfil. The F-111 Aardvark could perform strategic missions, while its capacity for forward deployment made it a useful strike aircraft in ways that a strategic bomber could not necessarily match. The Blinder provides another reference point for that forward-deployed strike role. In this interpretation, TSR-2 represented a next generation of British strategic bombing capability in some respects. A judgment about the better aircraft therefore depends on which mission the comparison assumes.
