Those 2 years are very interesting and you've probably felt like you're onto something. Stuttering is so deeply ingrained in your mind that returning to your hometown is always gonna be challenging as you have so many negative or even positive associations to stuttering. We are being of habit and stuttering is probably the most relentless habit I will ever form. What helped me immensely were psychedelics like LSD and DMT while I have experimented with others. It helped in both ways you described, the new city type and rising above the suffering of being a stutterer even though that wasn't my intention and I wouldn't even entertain such a thought before. Because that reality shattering experience will reset your mind like no other and while you still have those old pathways they are very vague and you have a lot of freedom to create new associations even if you're in your hometown being in same situations. There is novelty everywhere again and that's why people say they feel reborn. Although I had experiences where I would forget how to stutter for months after a trip I seem to return to it and in those process of starting to stutter again I would learn so much about my psyche and why I stutter in the first place. Not stuttering is very fun like you said but that enjoyment of being "normal" and I can tell you I had the darkest existential crisis after a few years of not stuttering and starting to feel the same suffering within life even though my issue is gone. After that I would trip and focus on accepting all of myself, that includes both the stutterer and fluent me along with many other versions and you come to the conclusion after a while that you are every version of yourself and none of them and all of them are perfect and serve a purpose. This all sounds annoying probably it's just bunch of meaningless words but the experience itself is very real and meaningful. Stuttering comes in phases nowadays that I can't predict but I've come to truly enjoy the stuttering phase as in those the mindset and emotional aspect are much more dense and rich. Yes you can socialize and be more free as a fluent speaker but it comes with this subtle shallowness that you can only notice if you pay attention. I experienced the thing that we sacrifice for fluency, the thing you sacrifice for stuttering is just more apparent. Stuttering is definitely an acquired taste that takes a long time to aquire but I believe psychedelics helped immensely. I saw someone on this thread mention being mindful and it's a very hard thing to do but worth developing. It's about not being the one who suffers but the one who observes the suffering.
