Maybe I'm biased as someone living much further north, but it seems to me that Sweden and Finland have more strategic geographic importance than Hungary, at least as long as Ukraine doesn't fall completely (ie as long as Russia doesn't get a common border with Hungary).
Without a shared border with Russia, Hungary's usefulness in a conflict would be relatively limited for Russia. On the other hand, for it would be highly dangerous for Hungary to willingly align with Russia, as that would make it likely that a future conflict would be fought on their territory.
As long as Sweden and Finland remain neutral, they are at risk. Putin has shown that he is willing to use military force to grab land. Should he grab Finland and Sweden, he would effectively control the Baltic sea and also have bases that can reach Western Europe much more easily than he can at the moment.
On the other hand, with Finland in the alliance, Nato has a highly defensible (for Nato) shared front with Russia, in the case of a conflict.
Also, keep in mind that Finland + Sweden together has a greater population than Hungary as well as maybe 5x the GDP, and that while Hungary is moving towards totalitarianism, Sweden and Finland both have long democratic traditions, low corruption, etc.
> Sweden and Finland both have long democratic traditions
Very different ones.
Sweden has been independent forever and a democracy since 1921.
Finland was first a part of Sweden, later an autonomous part of Russia. In 1917 it became independent and a democracy. However, a bloody civil war followed. Although it did not last long, consequences in politics and society remained visble for generations. Between 1945 and 1990 there were limitations to the democracy. They would only do what was assumed not to annoy the Soviets too much. Party leaders and prime ministers were chosen according to that principle. Freedom of the press existed only as long it was not too negative about the Soviet Union.
While it changed with the end of the Soviet Union in 1990, they could join EU 1995, applying for NATO marks only the real end of that period that they could not freely determine the direction of their country.
By your definition (ie universal suffrage), the USA has only been democratic since 1965. So that makes Sweden's democracy twice as old as the US democracy.
But that is not what I mean when I say "democratic traditions". Especially for countries that introduce democracy gradually and (mostly) peacefully, I consider the whole transition period to be part of those traditions. A country like Sweden had more than 100 years (1809-1921) of public discussions and political manouvering to build up the institutions, culture and education that provide stability, legitimacy and public support to such a system.
Finland underwent a similar development from the end of the Civil War to 1990, which mean that in 1990 the democratic institutions and traditions had already been built.
Other Warzaw pact countries had varying amounts of democratic traditions at that point. Some (like Hungary) had seen little democracy. Others, such as Czechoslovakia had been mostly democratic in the interwar period, while most had seen some democracy and some authoritarian rule in that period.
I would argue that those traditions from 100 years ago play a part, even today. And in the case of Sweden vs Finland vs Hungary, Sweden and Finland both have very strong traditions for democracy (even if the age of those traditions are different), while for countries like Hungary and Ukraine, those traditions are still shaky.
