For what it’s worth, I always found Pulaski’s lack of instant mesh with the TNG characters produced some interesting sparks that at least breathed some life into the scripts that wasn’t there before, a side effect of the “no interpersonal conflicts” edict from Roddenberry when the show started. It gave her a bit more life to start with - Crusher came back, and they didn’t really develop her too much more, while Pulaski developed over just that one season.
Honestly, I never saw Pulaski's initial period of not instantly meshing with the rest of the TNG character as 'interpersonal conflict'. I saw it more as a new environment to which Pulaski would have had to adjust to.
Even with most/all of humanity's issues gone centuries prior and interpersonal conflicts between humans resolved, that doesn't mean you will necessarily 'mesh' with other people instantly - aka, there would be some personality differences that one would have to adjust to... but otherwise, people were in fact not just tolerant, but accepting of those differences regardless. Getting used to them may take a period of time either way - and its not necessarily an interpersonal conflict.
The only thing that could be described as such would be Pulaski's initial prejudice towards Data, but that could simply be lack of exposure to other Androids (of which Data was a first in UFP to be integrated as part of society as a whole) and lack of existence of rights inside UFP for Androids at the time... but as we saw, Pulaski did change her behavior towards Data very quickly.
Yes, her initial prejudice towards Data was not something I liked, however, as the year progressed, she got more development (arguably more than Crusher did in the whole of 7 seasons) and was (in my view) a better character than Crusher was... and in fairness, I saw Pulaski as a more 'competent' doctor than Crusher.
Pulaski managed to offer Geordi an opportunity to have real eyesight... and while she did say it wasn't without risk, it was something that Pulaski never managed to do.
Real-life wise I suppose they wanted Geordi to remain blind so in-universe, he may have opted out of having the surgery due to those unknown risks (which in fairness were smaller becauser Pulaski said she did the procedure twice before).
From a character POV... I think Pulaski got a bit more development and seemed to have been able to be incorporated into other story arcs better and contribute with greater medical skill/proficiency than Crusher... whereas Crusher just 'seemed to be there' and did things in a fairly unremarkable capacity.
