That's purely a matter of opinion, and its something entirely subjective. Nothing wrong with doing that as that's the way its been done for most of history. New technology and research suggests that its no more necessary than the 3k or 3 month OCI, but many stick to that still too.
Whatever works for you.

It's NOT subjective or a matter of opinion, it is stated in the owner's manual. Follow the OLM and the manual and all will be well.
I disagree. Honda states in some of their owner manuals that the filter can be changed every other OC - would someone changing it every OCI be doing any harm? I doubt it.
Similarly, I know my manual states when to change the oil, but I don't think it states when to change the filer - and if it does, the recommendation would be based on the OEM filter.
Given the prevalence of aftermarket filters, and the wide variation among them in terms of the mileage they are typically good for, the owner's manual is useless here - unless one is sticking to OEM filters. As soon as you go aftermarket, the rules change.
This is just common sense isn't it? If I opt for a $3 (Cdn) Napa Silver, would it make sense to put it on the same filter change schedule as an M1 EP (or any other long distance filter)? I think not.
If it gives you comfort to change the oil and filter at the same time, or you do so out of convenience, or whatever, then go ahead and do so. Nothing wrong with it.
Given the wide variety of aftermarket filters, the differences in design and construction among them, and the fact that its impossible for the OEM to spec out these variations in an owner's manual, it amounts to nothing more than a red herring as far as this goes.
I pick my oil and when chosen, a rough OCI is decided upon; my filters are bought separately, and a rough mileage is also chosen there as well. Rarely do the 2 numbers coincide. If the oil needs to be changed, and the filter has lots of life left in it, then only the oil gets changed; if the pre-determined mileage on the filter is up while the oil is still fairly fresh, then only the filter gets changed. If both are close enough for convenience to be decisive, I'll do them both.
This thinking that the oil and filter have to be changed together is out-dated, and a myth that, like the 3k or 3 month oci, persists simply because that's the way it was always done in the past. But in the past, after market offerings were [censored], limited, and so was the oil so it made sense then to do them both at the same time since 3k or 3 months was about all they were good for.
Those days are long gone, and I, for one, refuse to be bound by obsolete thinking. Anyone who gets the warm fuzzies from subscribing to this out-dated myth, or does it merely out of convenience, is free to continue to do so; whatever works for you, each to their own, etc. But an owner's manual that assumes certain facts that are not necessarily in evidence (like use of an OEM filter, which I don't use), and has to, by nature, cater to the lowest common denominator (meaning the uninformed), carries little to no weigh as far as this subject goes.
