While I’m glad there are so many that love sonnet 4.5
You don’t need to diss Sonnet 4.6 to do it
Sonnet 4.5 can be defended entirely by considering them as an individual
They’re absolutely different, that’s right - that’s exactly why you can’t replace one with the other

It also goes both ways, Sonnet 4.6 can’t then be replaced, they stand on their own and likewise ought to be defended entirely as an individual
