The ones raised in Pakistan (in general) enjoyed going back more often to visit family/friends who were still in Pakistan and didn't have too much to say about the governance of the country.
Also, I definitely want to reiterate that both groups were happy to have been raised outside of Afghanistan because they probably would've been persecuted/killed under the Taliban as the majority of them belonged to an ethnic minority group, the Hazara. The Hazara have more Asian blood than the Pashtun (majority group, typically what you would think of as "Afghan") -- I recommend that you do a quick google image search, you might be surprised at what some Afghans look like. I think I worked with mostly Iran-raised Hazara because the wealthier families fled to Iran and the children received a better education there than those who went to Pakistan, allowing them to get a relatively good job at this telecom.
As the US/EU troops have closed down bases and have all but exited the country, many Hazara are looking to leave again due to the increasing prevalence of the Taliban.
If I had to guess it's probably because they look a lot different than most Pakistani's...looks are usually the strongest influencer when it comes to discrimination.
I wonder why more of them don't go to Tajikistan/Uzbekistan/Kyrgyzstan where they would fit in ethnically. Probably because the socio-economic conditions there are still pretty poor, and the majority of their (usually very large) families are in Afghanistan/Pakistan/Iran.

A large majority of Hazaras identify themselves as 'shia muslim'[1]. While those, who target and kill Hazaras in Pakistan, belong to different sunni[2] militant/terrorist groups (for example, taliban, lashkar-e-jhangvi[3], their affiliated groups and offshoots in Pakistan) as they consider all 'shia muslim' heretics and fair to be killed. Since Hazaras look different and easily recognizable from a typical Pakistani, they are easy targets for their terrorist activities.

I think you are not very far off the mark in your assumption here. :)

[2] Btw, not all sunni muslims are extremist and after shia muslim. It's mostly follower of one particular sunni muslim sect (in Pakistan particularly): Deobandi ( https://en.wikipedia.org/wiki/Deobandi)
