Best way to see if it fits your needs, try it out.
That is the plan. I doubt I will notice any real differences between Debian 12 and Debian 11. Debian 11 is still "current" until the end of the day, I guess.
I am experimenting with Debian as a potential future desktop. I use ordinary, mature, well-tested services and features in my Debian servers. I doubt anything I run on Debian 12 will go through poorly tested code paths, but I do not plan to update anything important for a while. That is one important reason why Debian 11 is still maintained and supported.
I know what these kind of releases feel like. It is a combination of utter exhaustion coupled with a weird combination of excitement and dread. Half of you wants the entire world to see it and try it out and use it and be excited and happy. Right NOW! The other half of you wants the take-up to be a very slow ramp, so you are not surprised by THE bug with a bizarre corner case that QA missed but has a subtle widespread side effect. Those kinds of bugs can drag everyone back in the middle of the night. You have to deal with it without compromising release quality. The "tiger team" starts to address the bug while everyone else drains a quick cup of coffee and dives in to help customer support or pitch in wherever needed.
... Big releases can be very stressful and challenging, but there is an unmatched reward that comes from working with great people and making great stuff, too. By the way, I never stayed up an entire night without sleep when I was young or even in college. I always managed to grab a couple hours of sleep. The first time I ever stayed up all night was the night of a problematic major product release.
In the free software world, someone probably finds the bug and suggests a fix in half an hour. :-(
P.S. I want to say something about great teams and leadership, too.
After that problematic release when I was treated to my first all-nighter, the company leadership rewarded everyone for their hard work. What impressed me most was that they also recognized and rewarded the families of the employees. Those families had worked very hard on the release too - sacrificing their loved ones' time and taking on a lot of the work at home so that we could get that release out the door. It was a great place to work, with great people. May you be so fortunate to have a few experiences like that too.
